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.

My Kid Wanted Video Games. I Was Against It. This Console Gave Us Both the Win
The movement-based Nex Playground might be the antidote to parental screen time guilt.
When our 8-year-old started asking for video games, I knew we were about to engage in an uphill battle. Anytime we’ve been to friends’ houses with gaming consoles, he goes full zombie mode, then has an epic meltdown once the sensory overload wears off. And since he inevitably ropes his 6-year-old brother in, we’re essentially sealing both their fates.
So when our neighbors started raving about a movement-based gaming console called Nex Playground, my first instinct was to shut it down. The words «gaming console» alone were enough to put me in a mental block. Add in my own memories of Wii tennis sessions where I nearly took out the ceiling fan, and I was firmly in the «no» camp.
But after doing a little more research, I was intrigued enough to try it out.
Screen time isn’t something I take lightly. With three kids ages 2 to 8, my husband and I have always been intentional about how and what they watch. They don’t have their own tablets, and most of their screen time happens on our family TV, which means whatever the oldest is exposed to quickly trickles down to our toddler. So anything we bring into the house has to work for all of them. Tall order, I know, but the Nex Playground gets surprisingly close.
Getting started is easy
The console itself is refreshingly simple. It’s a small cube, slightly larger than a Rubik’s cube, with a circular camera and motion sensor, a light indicator and two ports for power, and an HDMI connection to the TV. There’s no controller beyond a basic remote for navigating menus. For most games, your body is the controller.
Setup is quick. Plug it in, connect it to your TV, and you’re ready to go. It doesn’t store video or upload footage to the cloud, which was an immediate plus. It also comes with a magnetic privacy cover that you can put on the lens when it’s not in use.
At $250, it’s not cheap, but it’s less than some of the popular gaming consoles for this age range, like the Nintendo Switch 2. That gets you a five-game starter pack: Fruit Ninja, Go Keeper (soccer), Starri (think Guitar Hero for your whole body), Party Fowl (an AR emoji frenzy) and Whack-a-Mole. Additional games require a subscription: $89 a year or $49 for three months, which unlocks a library of 50-plus games and counting. New titles dropped even as I was writing this.
The library spans a surprisingly wide range. There are board game adaptations like Connect Four and Candy Land, character-driven games with Peppa Pig, Bluey and the Ninja Turtles, and sports like baseball and, yes, tennis — minus the ceiling fan hazard. There’s even parent-friendly content like Zumba workouts, which I may or may not have fully committed to on a rainy afternoon.
Even my toddler has gotten in on the action, mostly bouncing her way through Hungry Hungry Hippos when her brothers finally concede.
Gameplay is where it wins
The movements range from swinging your arms to keep a ball in motion, hopping or full-body launches that are far more aggressive than what the game actually requires. (I’m not about to tell the kids otherwise.) After a 45-minute session, my kids are tired and sometimes even drenched in sweat. The Nex Playground entertains and burns energy in one fell swoop.
The graphics also seem intentionally simple and arcade-like, which fits the minimalist play experience. There’s no POV storyline to get lost in, no leveling up into a new world at 9 p.m. on a school night. Some games keep score, which awakens my kids’ competitive streak, but the vibe is more collaborative and hasn’t been the catalyst for more fighting like other games. If anything, it’s done the opposite.
I still don’t love defaulting to a screen when my kids are bored, so we try to use it in moderation. In our house, piano practice is the only thing that unlocks weekend play time, and the fact that they’ll sit at the piano for a full hour tells you everything you need to know.
The verdict that matters most
But the real test: Does it hold up to an 8-year-old who was dead set on a Nintendo Switch?
Short answer: yes. At least for now. He’d still pick the Switch if you asked him, but not for the reasons you’d expect.
«The Playground is more tiring,» he told me, which only helped seal the deal for me. His current favorite is Homerun Hitters. «It’s basically a baseball game where you go against ranked global players. Me and my brother are really good at it.»
This from a kid whose primary hobby is annoying his younger brother. The fact that he said «me and my brother» as a collective was an unexpected bonus.
The Switch may still show up on the Christmas list this year. And realistically, I know I’m on borrowed time. As kids get older, «cool» becomes the currency, and a motion-based cube probably won’t hold up against an Xbox or a Switch once playdates turn into side-by-side gaming sessions.
The Nex Playground isn’t a replacement for those. It’s more of a detour; it gives them a taste of gaming without all the usual side effects. Even if I do eventually cave, I can still see it sticking around for the occasional family game night or as a rainy-day sibling diffuser.
In the meantime, I’ll relish this simpler version of gaming while I still can. He’s not exactly rushing me to return this review unit. More importantly, neither am I.

Don’t Wait for New Emoji in iOS 26.4, Here’s How to Create Them on Your Own
If your iPhone has Apple Intelligence, you can create your own emoji now.
Apple will likely add new emoji to your iPhone when the company releases iOS 26.4. Those new emoji could include an orca, a distorted smiley face and more. According to Emojipedia, there are 3,953 emoji with more on the way. The current list of emoji include smileys, sports players, weather conditions and flags. But there’s no emoji for a dog wearing pajamas, a plate with burgers and fries and many other things. But if you have Genmoji on your iPhone you can create these emoji and many more.
Apple released iOS 18.2 in 2024 and the company introduced its own emoji generator, called Genmoji, to Apple Intelligence-capable iPhones at that time. The Unicode Standard, a universal character encoding standard, is responsible for creating new emoji, and approved emoji are added to all devices once a year. With Genmoji, you don’t have to wait for new emoji to appear on your iPhone each year. You can just create them as you need them.
Read on to learn how to use Genmoji on iPhone to create your own custom emoji. Just note that only iPhones with Apple Intelligence, like the iPhone 17 lineup, can use Genmoji at this time.
How to make custom emoji
1. Open Messages and go into a chat.
2. Tap the plus (+) button next to your text box.
3. Tap Genmoji.
You can then type a description of an emoji into the text box near the bottom of your screen and tap the check mark on your keyboard to enter that description into Genmoji. You can also tap different suggestions and themes that are right above the text box. And with iOS 26 or later, you can also combine and use emoji to create others rather than describing a new emoji or using suggestions.
Your iPhone will generate a series of new emoji for you to pick from according to your description, and you can swipe through these new emoji. When you find the one you want, tap Add in the top right corner of your screen and the new emoji will be available to use as an emoji, tapback or a sticker. Now you don’t have to wait for the Unicode Standard to propose, create and bring new emoji to devices.
For more iOS news, here’s what to know about iOS 26.3.1 and iOS 26.3. You can also check out our iOS 26 cheat sheet for other tips and tricks.
