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.

I Got Up Close and Personal With Boston Dynamics’ New Atlas Robot
Before Atlas takes its first steps into the world of work later this year, I found myself face-to-face with CES 2026’s most talked-about robot on the show floor.
When I say that I went hands-on with the new Boston Dynamics Atlas robot, I mean that I actually held hands with it. This humanoid robot, which CNET just awarded the Best Robot of CES Award, is one of the most advanced in the world, and I couldn’t pass up the opportunity to get up close and personal with it.
This product version of the robot, which is set to be shipped to Hyundai factories imminently to start working, has been the talk of CES this year. The specific Atlas robot I encountered was a static model that wasn’t turned on or fully operational. Our interactions were, therefore, sadly one-sided. Still, I ran my hands over its soft-touch plastic shell and gently prodded at its finger joints, wondering how it would feel if they gripped me back.
People tend to have varying feelings about humanoid robots — understandable given that they are built to some degree in our image, while also usually being stronger than us, with «brains» that we don’t fully understand. Atlas definitely evokes contradictory emotions for me — even more so when I stood face-to-face with it.
I’m in awe of the engineering, a little fearful of its capabilities, hesitant about what it could mean for the future of humanity and charmed by its design and styling. The periwinkle blue iteration of Atlas that I met on the show floor at CES 2026 almost bears more resemblance to a Dyson product than it does the industrial robots that defined Boston Dynamics’ early days, when it was best known for its work with DARPA.
«There’s a lot of really specific things about this robot that probably look a little weird,» said Zachary Jackowski, Boston Dynamics VP and general manager of Atlas. He pointed to the legs, which he described as «like nothing anyone else was doing.»
Atlas’ thighs are narrow set and in line with the torso, while the calves are wider set, attached to their upper counterparts with a circular joint. This robot is, in fact, all subtle curves and soft lines. There are no harsh edges or stark angles.
During a year when CES has been flooded with humanoid robots, Atlas definitely does stand out due to its design. It appears both less classically human and less industrial than some of its peers, while also lacking the often intimidating, featureless faces they tend to exhibit. Instead, it has two low-set cameras resembling eyes placed where you’d usually expect a mouth to be. Its face is a perfect flat circle, defined by an LED halo that gives it a somewhat Pixar lamp effect.
I asked Jackowski why Boston Dynamics decided to skew so relatively unhuman with this version of its humanoid. «Well, it’s not a human,» he said. «It projects the wrong first impression about a robot to have it pretend to be something that it’s not.»
Particularly in the early days of humanoids, he added, robots won’t have anything like human-like intelligence. People should look at it and see it for what it is — a tool for performing tasks safely and efficiently.
In fact, most of the design decisions were made to keep Atlas as simple, scalable and safe as possible, Jackowski said. I remark that there’s some irony in thinking of a humanoid robot as simple, given the complexity of the technology and development process to bring Atlas to life.
The key to making it simple, Jackowski said, is having a strong enough grasp of the technology to «accomplish the complex thing of building a humanoid robot,» but then being able to take it apart and understand that you can use fewer computers and actuators in it while achieving the same results.
And it’s essential to Boston Dynamics that Atlas is perceived as simple. After all, it’s a general-purpose humanoid, which might eventually be sent far and wide to fulfil all manner of roles. Jackowski calls it the «ultimate generalist.»
Simplicity aside, there are aspects of Atlas that Jackowski believes set it apart from other humanoids at the show. «The repairability of this robot is crazy good,» he said. «The runtime is crazy good. The strength is unlike anything.»
From working in Hyundai’s manufacturing plants, Atlas’s job trajectory is to eventually graduate to many of the same industrial environments where Boston Dynamics’ Spot robot works, before moving to bussing tables in the service industry and eventually into the home. The robot will evolve between now and then, Jackowski said. However, this could be an early glimpse of the type of humanoid that will eventually be our housemate.
That’s some way away, though, which is probably for the best. As I gaze up at Atlas, which I’d guess is around the same height as my husband, my feeling is that, however impressive Atlas is, I’m still not ready for it to move in.

This Star Wars Dartboard Has a Secret That Will Stop You From Using the Force to Win
This cool dartboard has cameras to track your score and keep you honest
Right in the middle of the high-tech show floor at CES 2026 sits a pub called the Bull and Barrel with some of the coolest dartboards I’ve seen. Target Darts was showcasing its collaboration with both Star Wars and Xbox. Darts may not be for everyone, but I love «shooting some arrows» in my basement with the family. I also love anything Star Wars themed, so these tick a lot of boxes.
The basic Star Wars set comes with a branded board and wall protector that resembles the cockpit of the Millennium Falcon and costs $200. The board is of very high quality, with a tight-knit sisal fiber face, and the protector is thick enough to keep stray shots out of your drywall. The graphics are cool too, with nods to the original Falcon and even have the gold dice hanging above.
The big tech twist to this board, though, is the Omni light ring around the outside. It uses four cameras to track your dart’s position, then sends that info to an app that keeps score. The scoreboard is crisp and clear and uses the voice of legendary darts announcer John McDonald to narrate your game. It’s pretty great to hear his voice announce my terrible scores.
The Omni also allows you to connect with other players worldwide via shared scoreboards. I love the idea of my dad having a board at his house or playing a match with me at my house. It adds a feeling of community to home darts that you don’t normally get outside a pub or bar.
The Omni is a much more expensive proposition than the Star Wars set, coming in at $650, but if you’re serious about the game and a Star Wars fan, it looks to be a great investment.
