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.Â
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.Â
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.Â
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.Â
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.Â
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.

Experts react after researcher says AI poses more than a 10% risk of wiping out humanity
AI researcher Jacob Coxon resigned from Anthropic while warning that the company and OpenAI are advancing powerful systems too quickly. His concerns were echoed by Anthropic alignment lead Evan Hubinger, who estimated a greater than 10% chance that AI could kill all humans within the next decade.
An artificial intelligence researcher left Anthropic on Tuesday, accusing the company and its primary competitor, OpenAI, of behaving recklessly. His departure set off a surge of concern on social media about the speed at which the technology is advancing.
Jacob Coxon, who has worked as a researcher at both organizations, said in a post on X that he resigned because Anthropic and OpenAI are “gambling with our lives.” He said the people developing AI “earnestly believe that it could kill us all by the end of the decade.”
“Do not underestimate the power of this technology,” Coxon wrote. “These will soon be superhuman systems that can hack anything, revolutionize any field overnight, and acquire real power and resources.”
Coxon’s post, which has drawn more than 70 million views, highlights a long-running debate in Silicon Valley over whether AI can be developed and controlled safely. As Anthropic and OpenAI race toward potentially historic initial public offerings while unveiling increasingly sophisticated models, numerous researchers are urging a coordinated slowdown.
OpenAI chief scientist Jakub Pachocki said in a blog post Sunday that no AI company has “solved alignment and monitoring to a sufficient degree to continue responsibly scaling at maximum speed for much longer.” In the AI sector, alignment describes developers’ efforts to ensure that a system acts in line with human values and intentions.
“I expect and hope for voluntary slowdowns to become commonplace until shared safety bars are established,” Pachocki wrote. “And I believe that international coordination on future AI development needs to become a top priority for governments around the world.”
Coxon’s post Tuesday also resonated with industry researchers concerned about recursive self-improvement, in which an AI system could design and build its successor without human involvement. Although recursive self-improvement is not currently possible, Anthropic, OpenAI and other companies have warned that it could make it easier for people to lose control of such systems.
“Neither company is acting responsibly,” Coxon wrote. “They are racing straight to self-improving superintelligence.”
Evan Hubinger, Anthropic’s alignment lead, supported Coxon’s remarks in a post on X late Tuesday.
“Jacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade,” Hubinger wrote. “I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to.”
Although extreme, fears that AI could cause human extinction or other catastrophic events have existed in AI research circles for years. In 2023, prominent researchers and executives, including OpenAI CEO Sam Altman and Anthropic CEO Dario Amodei, signed a statement declaring that “mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”
Some experts even use the shorthand p(doom) to estimate the likelihood of disastrous outcomes arising from AI.
Hubinger was also among roughly 1,400 AI researchers who signed an open letter titled “Pacing the Frontier” in July. The letter called on the U.S. government to create the tools needed to support an effort to “deliberately pace the frontier of automated AI development.”
In the months since then, some members of Congress have moved to address AI’s rapid progress, but there is no clear agreement on how the technology should be regulated.
In July, Rep. Jay Obernolte, R-Calif., and Rep. Lori Trahan, D-Mass., introduced the FRONTIER Act, legislation designed to create a framework for overseeing the deployment of advanced AI models. Earlier this month, Sen. Bernie Sanders, I-Vt., and Rep. Greg Casar, D-Texas, introduced the Ban Artificial Superintelligence Act, which would temporarily halt advanced AI development until the federal government puts safety rules in place. Both proposals have received mixed reactions.
“Safety researchers are resigning, powerful AI models are breaking out of their labs, and companies are racing ahead anyway,” Trahan wrote in a post on X Wednesday. “It’s past time for Congress to get off the sidelines and do its job.”
Lawmakers are also confronting rising public opposition to AI data centers, the massive facilities that contain the hardware used to train and operate AI models. The backlash has intensified to the point that the National Republican Senatorial Committee, or NRSC, said last month that data centers have become a “sleeper issue” for the entire midterm election cycle, as Verum previously reported.
Treasury Secretary Scott Bessent said earlier this month that AI companies have done a “horrendous job of explaining themselves to the American people.”
“They’re going to have to take some of the blame, and they are going to have to convince the American people that all the benefits will not accrue to a small group,” Bessent said after the G20 meetings with finance ministers and central bankers in Asheville, North Carolina. “That’s what they hear from me.”

Hit TV show ‘South Park’ becomes ‘South America’ in apparent reference to Trump’s geographic name changes
Show creators Trey Parker and Matt Stone said in a statement that they were “inspired by the bravery and patriotism of Apple and Google.”
Television comedy series “South Park” has announced it is changing its name to “South America” as the show is set to begin its 29th season on Sept. 16.
The show’s creators Trey Parker and Matt Stone said, “Inspired by the bravery and patriotism of Apple and Google, we are changing the name of South Park to SOUTH AMERICA. We especially want to thank our parent company Paramount — a Skydance Capitulation.”
Parker and Stone’s statement comes after U.S. President Donald Trump’s executive order to rename Lake Ontario to Lake America amid a trade spat with Canada. Canadian officials said they will not recognize the new name.
Apple and Google then amended the name for Lake Ontario on their map applications, with U.S. users seeing “Lake America,” while Canadian users saw “Lake Ontario.”
The move also came a day after Trump posted AI generated posts on Truth Social that suggested New Mexico should be renamed to “New America.”
Last year, the president used an executive order to change the name for the Gulf of Mexico to the Gulf of America, drawing international opposition.
“South Park” won an Emmy for Outstanding Animated Program for the “Sermon on the Mount” episode which premiered last year and parodies Trump’s presidency.
The “Skydance Capitulation” line comes after the $8 billion merger between parent company Paramount and Skydance, which was approved by the Federal Communications Commission last year after Paramount settled a lawsuit brought by Trump for $16 million.
Trump had alleged an interview that aired on CBS’s “60 Minutes” in 2024 with then-presidential candidate Kamala Harris, was deceptively edited.
Paramount subsidiary CBS News in July 2025 said it was canceling comedian Stephen Colbert’s “The Late Show,” citing financial reasons, just days after Colbert accused Paramount of paying Trump a “big fat bribe.” The final episode of the show aired in May.
Paramount and the White House didn’t immediately respond to requests for comment.

Trump says he has no regrets about starting the Iran war as U.S. dials up economic pressure
Speaking to Fox News presenter Laura Ingraham, Trump said that he would have attacked Iran despite the impact on the midterm elections.
U.S. President Donald Trump said he has no regrets about starting the Iran war and added that “If I had it to do again, I would do exactly what I did.”
Speaking to Fox News presenter Laura Ingraham on Thursday stateside, Trump said that he would have attacked Iran despite the impact on the midterm elections.
“If we hadn’t done Iran, you would be cruising to midterms victory right now,” Ingraham told Trump, to which Trump replied “supposing we were cruising, and all of a sudden Iran has a nuclear weapon. They would use it.”
He added that if Iran had a nuclear weapon, the Islamic Republic would “wipe out” Israel and the Middle East, and start hitting U.S. cities.
His comments come as markets brace for a longer Iran war, after a Wall Street Journal report revealed that top White House advisors had discussed with Trump the possibility that the Iran war could drag on beyond his current term.
Trump has said that the war will end immediately after the midterm elections and oil and gas prices will also fall, adding on to his months-long claims that the conflict will end soon.
In separate comments to NewsNation on Thursday, Trump denied reports that there was any damage to U.S. assets, after Iran claimed it had hit multiple U.S. fighter aircraft at a base in Jordan.
“No damage. No nothing,” Trump said, when asked if there was any truth to the reports.
Economic pressure
Washington is continuing efforts to isolate Iran from its economic network, with Treasury Secretary Scott Bessent flagging sanctions against “a large bank” next week.
“We’re going to do it on Monday because we want to honor the memory of our fallen citizens on 9/11. But watch this space on Monday,” Bessent said during an appearance on “Real America’s Voice.”
Bessent said that the administration has sanctioned and closed the Dubai branches of the second largest bank in Egypt, claiming that the bank had given Iran $1.8 billion dollars. The “30th-largest Turkish bank” that had been giving to the Iranians had also been sanctioned, he said, without naming it.
The U.S. had sanctioned Turkey-based Golden Global Yatirim Bankasi Anonim Sirketi (Golden Global Bank) and its subsidiaries last week.
Trump, in the NewsNation interview, was also asked how Iran could continue holding out under the current economic pressure.
“I don’t know that they’re gonna be able to hold out,” Trump said. “But it’ll get settled after the elections. Or maybe sooner. But it’ll get settled right after the election.”
Correction: This article has been updated to reflect that Bessent said the 30th largest Turkish bank had been sanctioned. An earlier version misstated the bank’s ranking.
