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.

Lemon8 and TikTok Could Be Banned. Here’s How the Apps Are Different
TikTok and Lemon8 are owned by the same parent company, but they offer different experiences.
TikTok faces another sale deadline Saturday, and unless a US buyer intervenes — or President Donald Trump extends the deadline again — the app could disappear for US users. If the ban goes into effect, TikTok wouldn’t be the only app to disappear: TikTok’s sister app, Lemon8, could be caught in the crossfire.
Read more: A VPN Alone Probably Won’t Bypass TikTok Bans. Here’s Why
Lemon8 is owned by ByteDance, the same parent company that owns TikTok. It’s one of the top Lifestyle apps in Apple’s App Store, and it has more than 10 million downloads in the Google Play store.
«Lemon8 is a lifestyle community focused app powered by TikTok, where you can discover and share authentic content on a variety of topics such as beauty, fashion, travel, food, and more,» the app’s description reads in both stores.
Here’s what you need to know about Lemon8.
Note: I reached out to ByteDance for this story, and the company did not respond for comment.
What is Lemon8?
Lemon8 is a video- and photo-sharing platform that eschews the vertical-scrolling format of TikTok in favor of a Pinterest board-style format. But what Lemon8 and TikTok do have in common is that both have Following and For You tabs to show you posts from creators you follow and posts the app thinks you will like.
Lemon8’s content is split into six topic tabs, plus a seventh tab called All. The other tabs are Fashion, Beauty, Food, Wellness, Travel and Home. These tabs can be found across the top of your screen, and tapping into these tabs shows you recommended and suggested posts.
Posts can be swipeable photo collections like in Instagram, or TikTok-style videos. Some creators add text to their photos to label clothing or a product. Some will also include the price of the item in the text.
How is Lemon8 different from TikTok and other apps?
Lemon8 is different from other apps in terms of what is posted and how it’s presented.
Lemon8 has a lot of influencer ads and product recommendations. It’s difficult to tell what is and isn’t sponsored content, and this appears to be the norm across the app. TikTok also has sponsored content, but usually these are marked as such in the bottom-left corner.
There aren’t a lot of memes or jokes on Lemon8 compared to other apps, either. You can find memes on Lemon8, but various hashtags associated with «memes,» like «funnymemes» and «catmemes,» have fewer than 1 million views (as opposed to hundreds of millions on Instagram). This could be because Lemon8 is still catching on in the US, but my suspicion is Lemon8 isn’t meant for memes. It’s meant to be more of a guidebook to help you achieve a certain lifestyle or aesthetic.
There’s also a lot of writing in Lemon8. For example, post captions might include instructions for a recipe or a deeper breakdown of an outfit. TikTok captions can have useful information, but those captions are more about connecting posts to hashtags to get more views and don’t necessarily add new information to the TikTok post. Lemon8 uses captions in a similar way to Instagram posts, but Lemon8 captions have one key difference from Instagram: templates.
Lemon8 lets you use templates for your posts to help you quickly format and to give you an idea of what to caption your post. There are caption templates for fashion, shopping finds, beauty, food and travel.
Lemon8 reminds me of a mashup between the magazines Martha Stewart Living, Muscle & Fitness and Travel + Leisure. You can find some useful tips in Lemon8 to help you achieve a desired aesthetic or find some vacation inspiration, but it’s not clear what is and isn’t an ad.
What are people saying about Lemon8?
People’s reaction to Lemon8 is seemingly positive so far. One TikTok creator posted a video calling Lemon8 «Pinterest, but interactive.» Another said Lemon8 is a combination of Pinterest, Instagram and TikTok.
However, this positivity could be artificially inflated. ZDNet reports that many TikTok posts about Lemon8 have described the app with similar language, making some believe ByteDance paid these creators.
And some Lemon8 creators’ claims make this theory sound more viable. One Lemon8 creator told Insider that ByteDance paid them to post on the app. Two other Lemon8 creators showed Insider emails that outlined the app’s payment structure.
Who owns Lemon8?
ByteDance, the Chinese tech company that owns TikTok, also owns Lemon8. According to ZDNet, ByteDance is positioning Lemon8 to be an Instagram rival as more users stop using, or abandon, Meta’s app.
According to the Wall Street Journal, a leaked internal memo from Meta showed that Instagram engagement was declining. ByteDance executives could be hoping to capitalize on this by giving Instagram users an alternative app in the form of Lemon8. And while Lemon8 was released globally in 2020, the app’s recent growth might show ByteDance’s gamble is paying off.
Will Lemon8 be banned alongside TikTok?
Since Lemon8 is owned by ByteDance, which also owns TikTok, it’s possible that the app will be banned alongside TikTok on April 5.
The law requiring the sale of TikTok could be applied generally to other apps that are owned and operated by ByteDance and its subsidiaries. When TikTok shutdown operations in the US in January, Lemon8 was shutdown alongside the app. If TikTok shuts down again, Lemon8 likely will as well.
Should you download Lemon8?
Even with a shutdown looming, Lemon8 is free, so you can download and try the app now before the sale deadline. Just know the app’s posts resemble instructional guides more than memes to share, and many posts feel like advertisements.
What’s Lemon8’s privacy policy?
Most of Lemon8’s privacy policy seems standard for social media apps. It states Lemon8 collects personal and location information to provide you with a better app experience. Some collected information includes your IP address and browsing history. But part of the app’s privacy policy might raise eyebrows.
«The personal information we collect from you may be stored on a server located outside of the country where you live,» the policy reads. The company has servers around the world, according to the policy, so your information could be stored in any of them.
This is different from how Lemon8’s sister app TikTok stores some user’s data. The company stores US-based user data in Oracle servers. TikTok CEO Shou Chew said ByteDance employees in China can access this data, but with «robust cybersecurity controls and authorization approval» overseen by a US-based security team.
For more on the TikTok ban, here’s what to know about the Supreme Court’s decision, here’s what could happen next and here are other apps users are flocking to.

Skip Your iPhone’s Lockscreen: Here’s the Hidden Flashlight Trick You Need to Know
A couple of taps can really make a difference on your iPhone.
Not long ago, your iPhone’s lockscreen would only allow two app shortcuts that you couldn’t change: camera controls and a flashlight toggle. However, iOS 18.2 allows you to customize these shortcuts to almost anything you might want. This small but impactful change is one of many ways iOS 18 supercharges customization for iPhone and iPad users. But what if you still want an easy-to-access way to toggle your flashlight without unlocking your phone?
Apple introduced an accessibility feature in iOS 14 that, once enabled, allows you to perform actions by just tapping on the back of your phone. The feature is called Tap Back and it remains a sleeper feature that’s sneakily hidden away in your settings menu. Enabling Tap Back essentially allows you to create a button on the back of your iPhone to perform an action without needing to take up any space.
Once you have Tap Back enabled, it doesn’t take long to see how much of a game-changer it can be with its added convenience. Below, we’ll show you how to set it up so a couple of taps on the back of your iPhone will let you launch just about anything you want.
For more, check out what’s in the latest iOS 18.4 release.
How to set up Back Tap on iPhone
Whether you want to link Back Tap with your flashlight, camera or launch a different iPhone app, the path through your iPhone settings begins the same way.
On your compatible iPhone (iPhone 8 or later), launch the Settings application and go to Accessibility > Touch > Back Tap. Now you have the option to launch your action (in this case, your flashlight) with either two or three taps. Although two taps is obviously faster, I would suggest three taps because if you fidget with your phone, it’s easy to accidentally trigger the accessibility feature.
Once you choose a tap option, select the Flashlight option — or a different action if you prefer. You’ll see over 30 options to choose from, including system options like Siri or taking a screenshot, to accessibility-specific functions like opening a magnifier or turning on real-time live captions. You can also set up Back Tap to open the Control Center, go back home, mute your audio, turn the volume up and down and run any shortcuts you’ve downloaded or created.
You’ll know you’ve successfully selected your choice when a blue checkmark appears to the right of the action. You could actually set up two shortcuts this way — one that’s triggered by two taps and one that’s triggered by three taps to the iPhone’s back cover.
Once you exit the Settings application, you can try out the newly enabled Back Tap feature by tapping the back of your iPhone — in my case, to turn on the flashlight. To turn off the flashlight, you can tap on the back of your iPhone as well, but you can also just turn it off from your lock screen if that’s easier.
For more great iPhone tips, here’s how to keep your iPhone screen from dimming all the time and canceling all those subscriptions you don’t want or need.
