Best 3D-Printing Accessories: Make the Most of Your 3D Printer
From tiny 3D-printer scrapers to giant machines, we have everything you need to level up your 3D-printing experience.
With some hobbies, extra tools and accessories can make them even more fun. 3D-printing is one, and the addition of a good set of extras will make your 3D-printing time much easier. Often these accessories are simple — a set of snips for cutting filament or a bit of glue to help bed adhesion — but there are also new pieces of hardware that can significantly improve your print quality or give your 3D printer powers it never had before. More than that, though, good accessories can make even the best 3D printers run above and beyond their normal scope.
I’ve amassed a huge number of helpful accessories after nearly a decade of 3D printing and have researched many others. Amazon is a great resource for finding basic 3D-printing accessories, and California-based MatterHackers has everything you need for more advanced upgrades and gear.
Best accessories for beginners
While every 3D printer comes with a paint scraper that you can use to remove models from the build plate, not all are created equal. Most 3D printer scrapers don’t allow you to get the blade low enough to lift a model without damaging the build surface. I use the Buildtak 3D printer scraper because it can swipe under the model without gouging down, making them pop right back up.
These little storage caddies are incredibly helpful for more than just storing shower products. The separate compartments make it easy to store all of your hex key wrenches, scrapers and filament cutters in a way that makes it easy to move them around your workspace with the handy handle. I have three of these in my workshop and I use them for 3D-printing tools, assorted glues and sandpaper. It makes life a lot easier.
A digital caliper is a helpful 3D-printing accessory, especially if you’re creating your own models. Most can measure details down to a thousandth of a millimeter, which lets you design with a high degree of accuracy.
Having a set of calipers also helps you measure your prints to make sure they’re printing in the correct size and shape.
Having a central place to store your materials is important to keep them safe and dry. These cabinets from Home Depot are expandable and easy to build. They’re perfect for stacking your filament or resins safely, and if you add a small dehumidifier or desiccant packets, you can keep everything dry, too.
Most 3D printers come to you with a 0.4mm nozzle, which is fine for most uses. There are a lot of cool projects you can make with larger nozzles, though: Try making thick vases using a 0.8mm nozzle or detailed miniatures with a 0.2mm nozzle. Having a variety of nozzles will expand your horizons to no end.
These Mk8 nozzles are designed for the Creality Ender 3, but many printer companies either use the same Mk8 nozzles or variety packs of their own.
Magigoo is like a glue stick on steroids. It is specifically designed to hold 3D prints to the build plate while printing but comes loose easily when the bed is finally cooled. It’s incredibly satisfying to print models that are barely touching the build surface that act like they are held down with cement. A small bottle goes a long way too, so it’s worth the price.
Did you know that the 3D-printing community uses so much Aqua Net hairspray that Amazon’s «Frequently bought together» section shows filament and replacement printer beds? Aqua Net is used as a transition adhesive that both helps your filament stick to the build plate, and when it gets cold, makes it easier to remove. You have to be careful not to spray it onto any moving parts, but if you take off your removable build plate and spray it gently and evenly you will see better results immediately.
Models often have sharp edges when they first come off of the build plate, especially if you’ve used a brim to anchor them down. A deburring tool like this smoothes those edges with a simple swipe across the corner. It takes a little getting used to, but if you’re making something for people to handle, a deburring tool is a must.
If you live here in the US, you may well have a set of hex wrenches that you use for most things. However, 3D printers are made using metric measurements, and not inches, so they will either be loose and damage the nut or not fit at all. A good set of metric hex wrenches are affordable and make 3D printing easier.
Desiccant is a much needed tool in the fight against moisture. Even the best 3D-printing filament can be degraded by absorbing too much moisture, and if you live in a damp climate, storing your filament in a cool dry place with a desiccant pouch is a great way to keep it usable for longer. These pouches are a little pricier than some, but they can be recharged by heating them up so you can use them again and again.
Like the hairspray, glue sticks help hold a print down, while also adding a barrier between the print and the plate. Some materials stick a little too well to a build plate and can tear a mat or even crack a glass plate. Glue sticks are water soluble too, so it’s easy to wash off with soap and water.
Accessories for intermediate and advanced users
If you’re hoping to print a filament like ABS, you’ll need your 3D printer to be very hot with no breezes. If you live in a particularly cold climate an enclosure is a helpful way to warm up the area around your 3D printer without having to pay a fortune on heating bills. The Wham Bam HotBox has two sizes, so even if you have a bigger machine you can reap the benefits of a warmer build area.
One of the best upgrades to be released in recent years is the Revo rapid change system from E3D. Available for a huge number of 3D printers, this hotend replacement adds the ability to quickly swap out your nozzles without the use of wrenches and pliers. You can remove the filament, let the nozzle cool down and twist it off with your fingers.
Being able to easily swap nozzles opens up new printing techniques with larger nozzles for strength and smaller ones for detail. It is a must-do upgrade for any compatible machine.
Nozzles are consumable in 3D printing and you can expect to use them up fairly frequently. If you print materials with abrasive materials such as carbon fiber, wood or even glow in the dark, your nozzle could be destroyed in just one eight-hour session. The ObXidian nozzle is specially hardened to reduce wear and tear and keep your nozzle printing for much longer.
It’s also a part of the Revo system I just mentioned, so can be easily swapped out for different sizes or other nozzles easily.
The Palette 3 is a multimaterial unit that lets your standard 3D printer print multiple colors or types of filament. It opens up a huge amount of variety in your 3D printing and can help you create a truly unique model. You can even take an existing digital model and «paint» colors onto it so that when it prints, it is a multitude of — well up to eight — colors.
The RepBox is a community favorite for a number of reasons. The creator is an awesome advocate for 3D printing and the box itself is a fantastic design that can be mounted or sat on a workbench. The RepBox holds six 1kg rolls of filament and comes with several dehydrating cases to keep them fresh. The filament is fed out of the box directly into a Palette system or multiple printers without ever touching the moist air.
3D printer accessories FAQ
What’s the best 3D-printing tool for beginners?
When you first start 3D printing, the most important thing to get right is your first layer. It takes time to get the build plate level enough to print consistently, so any tool that can help with that is important. Any of the bed adhesives in this list will help your first layer lay down better, and make it easier to remove the print once it is done.
Glue sticks and hairspray may seem like low-tech solutions for a high-tech machine, but they work and they’re cheap.
How does nozzle size affect 3D printing?
Nozzle size determines how much material you can push through at any given time. The standard nozzle has a 0.4mm hole in it, but there are nozzles available from 0.2mm to 0.8mm and beyond. A good rule of thumb is that if you want a stronger print, go big, and if you want detail, go small.
I would say that there is a move to replace 0.4mm nozzles with 0.6mm nozzles as a standard, as you lose very little detail in the change, but the models print quicker and tend to be stronger too.

TikTok’s Sexy Affair With National Parks Isn’t Clickbait. It’s a Wake-Up Call
Social media thirst traps are spotlighting a funding crisis for public lands. And millions of people are paying attention.
National parks, gay country music and thirst traps have a lot in common, at least on the internet.
Hundreds of TikTok posts combining sexually explicit audio, comical memes and stunning views of nature have flooded social media feeds. The viral trend coincides with President Donald Trump’s unprecedented funding cuts targeting federal parks, forests, monuments, seashores and trails.
The message of #ParkTok and #MountainTok is G-rated: to conserve and protect public lands. The raunchy content is merely a wrapper to lure followers and get that message in front of as many people as possible.
At first glance, the TikTok fan accounts for Yellowstone and Joshua Tree — among dozens of other national parks, forests and recreation sites — appear to be competing in an unhinged brawl. Some commenters speculate that federal park rangers or marketing strategists have gone rogue to garner outside financial support.
But the unofficial accounts, which are growing in number daily, are run by independent content creators with no affiliation to the government. According to the National Park Service’s Office of Public Affairs, the NPS has no official presence on TikTok, as there are no terms of service between federal agencies and the platform.
«Viral trends focused on national parks can certainly boost park visibility and drive increased interest and awareness,» the National Park Service told CNET in an email. «We appreciate the enthusiasm for our nation’s parks and the creative ways individuals share their experiences online.»
And millions of social media followers say they’re here for it. Promoting the country’s vast landscape and its preservation for future generations could serve as a kind of spiritual uplift in dark times.
Nature is sexy; budget cuts aren’t
Far beyond the racy adult content, there’s a unifying purpose to posting videos of cascading waterfalls, colossal trees, seductive deserts and enchanting wildlife.
Researchers have noted that national parks are key to conserving biodiversity and supporting people’s well-being. And it seems everyone, not just nature nerds, can get behind these public lands: US national parks saw a record number of recreation visits last year, nearly 332 million.
«If you actually love all this stuff, you get attached to that beauty,» said Kim Tanner, the creator of the Joshua Tree fan account. «And then you realize you don’t want that beauty damaged.»
The Trump administration’s 2026 budget plan includes slashing more than $1 billion from the National Park Service. It also threatens to axe a whopping $33 billion from national recreation management programs and conservation and preservation grants. The grants are critical to maintaining 433 individual areas of public lands covering more than 85 million acres, which are managed by the NPS.
The National Parks Conservation Association says the White House’s budget reductions are the largest proposed cuts to the National Park Service in its 109-year history and could «decimate at least 350 National Park sites.» Many have said Trump is laying the groundwork to sell off public lands and turn recreational areas over to state-level management.
According to Kristen Brengel, senior vice president of government affairs for the National Parks Conservation Association, the NPS has already lost nearly 2,500 employees, or nearly 13% of its staff, in what she calls a «brain trust exodus» of environmental experts.
«What’s happening right now, in trying to dismantle the National Park Service from the inside out, is more horrific than anything we’ve seen before,» Brengel told me.
Getting wild for the wild
TikTok is controversial, and so is sex. That’s precisely why trends like these have political capital, capable of attracting admirers and haters, and bringing everyone else into the conversation.
«The polarization on social media is reflective of our real-life political polarization,» said CNET social media reporter Katelyn Chedraoui.
The #ParkTok and #MountainTok creators, some of whom are former park employees, are all nature lovers who span the political spectrum. Many of the accounts openly denounce the administration’s threats against the parks and direct viewers to demonstrations or fundraisers, but the trend isn’t overtly partisan or activist-driven.
«Most of their posts work on a subconscious level, prompting viewers to think about the national parks and their own experiences with them,» said Chedraoui. «It’s simple but effective.»
In fact, the TikTok engagement around public lands originated before the budget cuts to the parks. The first three fan accounts — Mount Hood, Mount Rainier and Yellowstone — appeared right after the elections last November. Managed by three friends who are avid outdoor enthusiasts, the accounts put up posts early on that were a mix of comic relief and wilderness awe.
There wasn’t much thirst trap content then. «It was just waterfalls and vistas and sunsets,» said Jaime Wash, the creator behind the Mount Hood and Mount St. Helens fan accounts. Then, two of the creators started trolling each other, and folks loved it.
It was fake beef, but the diss-track template became a winning strategy. By January, the trend started picking up speed, with more fan accounts joining the fray. Over the last several months, the popularity of the posts has seen ebbs and flows — until fairly recently, when all of #MountainTok and #ParkTok blew up for their risqué content.
Private parts in public lands became a magic formula, a kind of viral virility, that the creators knew how to play up.
«Social media users are very used to brands acting unhinged on TikTok,» said Chedraoui.
A bridge over troubled water
Some critics have slammed the parody accounts, accusing creators of trying to monetize a legitimate cause, or claiming that the sexually charged content damages the parks’ reputations.
But according to the creators, who collaborate regularly in a group chat, making money wasn’t, and never will be, their intention. Wash told me that if at any point they do collect a payout for the content, they plan to donate the funds to the parks.
After gaining such a huge following, Wash said, she felt it was her responsibility to get people involved. In April, the Mount Hood fan account brought out followers to Portland’s Hands Off protest.
«We’re building a community to show that things aren’t helpless, that change can happen and we’re there for each other,» Wash said. And besides raising the alarm, the posts add comic relief and entertainment to a daily cycle of doomscrolling and anxiety.
Tanner told me that #ParkTok and #MountainTok can open people’s eyes, showing how fragile nature really is. By highlighting endangered animals and the environmental damage from logging, drilling and mining, the posts can help millions of followers understand what’s really at stake.
The stunning power of social media
Social media acts as a cultural barometer, unveiling public sentiment in real time and broadcasting issues that most resonate. Platforms like TikTok also give grassroots movements a megaphone, allowing everyday people to bypass traditional media filters and speak directly to broad audiences.
«We’ve seen digital action lead to tangible action,» said Sheila Nguyen, associate director of communications and engagement for the National Parks Conservation Association. «The more people who see that social media content, the bigger the pool of people who may speak up and the more collective impact we can have,» Nguyen told CNET in an email.
In fact, social media publicity has been shown to boost national park visitation. A 2024 research study found that positive social media posts that include photos or videos drive the biggest increases in visitation.
«The more people we can get into these parks, the better. That way, they can experience it firsthand, see it, fall in love with it, and then want to protect it,» said Tanner.
The National Parks Conservation Association urges people to sign up for alerts on its advocacy page so they can raise concerns with congressional representatives.
«We feel that Congress is the best option right now to get the administration to back off of these bad proposals,» said the NPCA’s Brengel. «Congress needs to be pushed to stop some of these terrible actions.»
Many TikTok creators I spoke with also said they’re advocating ways to hold elected officials accountable.
«It’s heartbreaking to think the places that I absolutely love may never be the same again,» said Wash, «and I want to do anything to stop that.»

Trump to Sign Bill Banning Deepfakes, Nonconsensual Images: What to Know
The bipartisan ‘Take It Down’ Act passed swiftly in both the Senate and the House, and has been championed by First Lady Melania Trump.
President Donald Trump is expected to sign the bipartisan Take It Down Act into law on Monday, a significant step in regulating the nonconsensual sharing of intimate images, including AI-generated deepfakes. The legislation aims to protect individuals from the harmful effects of such content, which has been increasingly prevalent in the digital age with the expansion of artificial intelligence.

What are deepfakes?
Deepfakes are realistic but fake images, videos or audio created using artificial intelligence to mimic someone’s appearance, voice or actions.
One widely reported example was a 2022 viral video of Ukraine’s President Volodymyr Zelenskyy. In the altered clip, Zelenskyy appeared to urge Ukrainian soldiers to surrender to Russian forces, a message he never actually delivered. The video was quickly debunked, but it raised serious concerns about the use of deepfakes in disinformation campaigns, especially during wartime.
Deepfakes have also been used to spread sexually explicit content or revenge porn.

What are the key aspects of the Take It Down Act?
The Take It Down Act prohibits knowingly sharing or threatening to share intimate images of someone without their permission, including digitally altered or AI-generated deepfakes. Here is a breakdown of the bill and what it targets:
- Criminalization of nonconsensual sharing: The act makes it a federal offense to distribute intimate images without the subject’s consent. The bill applies to both real and AI-generated content.
- Mandatory removal: Online platforms, such as tech and social media sites, are required to remove flagged content, including any copies of the material, within 48 hours of notification by the victim.
- Mandatory restitution: Violators will face mandatory restitution and criminal penalties such as prison time, fines or both.
- Protection of minors: The legislation imposes stricter penalties for offenses involving minors, aiming to provide enhanced safeguards for vulnerable individuals.
- Enforcement by the Federal Trade Commission: The FTC is designated as the primary agency responsible for enforcing the provisions of the act.
Who supports the Take It Down Act?
First Lady Melania Trump has been a vocal advocate for the legislation over the last several months, emphasizing the need to protect children and teenagers from the damaging effects of online exploitation. Her efforts included public appearances and discussions with lawmakers to garner support for the bill.
The bill, introduced by Sen. Ted Cruz (R-Texas), gained bipartisan backing, with cosponsors including Sen. Amy Klobuchar (D-Minn.) and Sen. Cory Booker (D-N.J.). It passed the Senate unanimously in February, followed by House approval in April with a 409-2 vote.
What are the criticisms and concerns about the bill?
While the act has been praised for addressing a growing issue, it has also faced criticism from various groups. Some digital rights organizations express concerns that the law could infringe on privacy and free speech, particularly regarding the potential for false reports and the impact on encrypted communications. There are also apprehensions about the enforcement of the law and its potential misuse for political purposes.
For instance, representatives of The Cyber Civil Rights Initiative, a nonprofit that supports victims of online abuse, voiced strong concerns about the bill, according to PBS News. The group criticized the takedown provision as overly broad, vaguely written and lacking clear protections to prevent misuse.
What are the next steps?
Trump is expected to sign the bill Monday at 3 p.m. ET. This act will mark Trump’s sixth bill signed into law so far in his second term. By his 100th day back in office, he had enacted only five, marking the lowest number of new laws signed by a president in the first 100 days of a term since the Eisenhower administration in the 1950s, based on an analysis of congressional records by NBC News.
The signing of the Take It Down Act represents a significant move towards regulating nonconsensual intimate imagery in the digital realm. While it aims to provide greater protection for individuals, ongoing discussions will be essential to address the concerns and ensure the law’s effective and fair implementation.
