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.

A Planet Parade Is Happening This Week: How to See 6 Planets In the Sky
Venus, Jupiter, Saturn, Mercury, Uranus and Neptune will all be in the night sky at the same time.
One of the coolest celestial events is happening this week, where six planets will be visible in the night sky at the same time. This phenomenon, known as a planet parade, occurs only a few times each year with varying numbers of planets.
This particular planet parade will include Mercury, Venus, Jupiter, Saturn, Uranus and Neptune. It’s just one planet shy of the full set, a phenomenon that is quite rare and most recently happened a year ago, in February 2025. You’ll need a telescope to see everything, especially since much of it will occur right at dusk, which will make a few of the planets harder to see.
When will the planet parade happen?
The Northern Hemisphere will get its best glimpse at the planet parade around sunset this week. This one will be particularly challenging for skywatchers because of light pollution, as spotting planets with the sun even partially up is more difficult. Your best bet is around 6:45 p.m. local time, and your window will be exceedingly short. Mercury and Venus drop below the horizon roughly 30 to 45 minutes later, so that’s all the time you’ll have.
The good news is that Mercury, Venus, Saturn and Neptune are all clustered together against the western horizon near the setting sun. Venus and Mercury will be right next to each other, and Saturn and Neptune will be clumped together nearby. That should make the four of them a little bit easier to spot, which is a boon for skygazers given the short window.
Jupiter and Uranus will be the easiest to spot and will remain in the sky long after the other four planets have dipped below the horizon. Uranus will travel across the southern sky alongside the Taurus constellation before dropping below the western horizon a few hours after midnight. Jupiter will follow a very similar path to Uranus, but it is hanging out with the Gemini constellation.
All told, the best dates to view the planet parade in the US, Canada and Mexico are Feb. 21 to 28. Before Feb. 21, Venus and Mercury will be too close to the sun. Once March begins, Mercury will drift closer to the sun again, dipping below the horizon before it’s readily visible. Once that happens, the five-planet parade will continue for about another week or so before Neptune and Saturn dip below the horizon, thus ending the parade and leaving only Venus, Jupiter and Uranus visible in the sky.
Will the planet parade be visible in my region?
Yes. We checked Stellarium’s sky map from several locations across the US, Mexico and Canada, and the planet parade was visible in every place we checked. According to Star Walk, the parade will be visible everywhere from Tokyo to London. We also checked the Southern Hemisphere, and it’ll be visible there as well. The dates vary based on location, but most places should be able to see it at some point between now and Feb. 28.
How can I find the various planets in the sky?
The image above gives you a general idea of where they’ll be in relation to one another, but the best thing to do is check out a sky map and plan ahead. We recommend Stellarium’s sky map if you’re on a desktop and Stellarium Mobile (Android and iOS) if you’re using your phone.
We recommend finding Venus first because it’s the easiest planet to spot out of the four that are near the sun. You can then use the app to find the other three. Jupiter and Uranus are alone in the night sky and will remain there after the other four dip below the horizon, so we recommend finding those last, since they’ll be around longer.
Will I need any special equipment to view the parade?
Yes. With four of the planets close to the sun, it will make them hard to spot with the naked eye, thanks to the light pollution. Uranus and Neptune are impossible to see without a magnification device of some sort, even in total darkness. A telescope is highly recommended. Astronomers suggest a minimum aperture of 8 inches and 50x magnification to get the best results. That is strong enough to see the rings of Uranus and Saturn. You need a telescope with roughly 150 times magnification to peep the rings on Neptune.
The usual space viewing tips also apply. Get away from the city to a place with as little light pollution as possible, since you’re already fighting the sun to see these things. And be very careful not to point your telescope at the sun, since that can damage your eyes. Try to pick a night with as little cloud cover as possible.
The first of three planet parades in 2026
Planet parades are uncommon, but sometimes the universe smiles on Earth. This year is going to be really good for planet parades, as three are expected in 2026. February is the first one. The other two are slated for April (five planets) and August (six planets). That means there are two more chances to watch a planet parade in 2026 if you miss the one in February.

If You Miss MTV and Dunkaroos, This Indie Game Is for You
Mixtape is an upcoming game about being a teenager when «everything meant the end of the world or the start of the world.»
At a record store in northern Los Angeles, I walked past racks of albums, a DJ spinning records and a stack of Dunkaroos, a cookies and icing snack that was all the rage in ’90s America. It felt like stepping back into an earlier era, the same one backdropping the upcoming game Mixtape, a story about a group of self-mythologizing teens hanging out before life pulls them away from their suburban American town.
In an amusing twist of fate, the main brain behind the game is an Australian rocker who didn’t step foot in the US until his 30s. Johnny Galvatron (a stage name and lead singer of the band The Galvatrons), creative director at studio Beethoven & Dinosaur, dreamed up Mixtape based on a blend of American youth culture that was broadcast worldwide, along with his own upbringing loving music of the period and playing in bands.
In a recording room behind the record store, I chatted with Galvatron about why a man from the Antipodes would tackle American youth, nostalgia through the lens of music and analog audio tech, the earnest wrongness of being a teenager and why the US is like Middle-earth.
I also got to play a short slice of Mixtape ahead of the conversation, a demo I originally saw at Summer Game Fest last year (but with a couple extra scenes exclusive to this event). It opened up with the game’s older teen heroine, Stacy Rockford, skateboarding down a winding road with her friends, lazily pulling kickflips and calling out oncoming cars in the golden hour before twilight, a fitting start for a game about the last days before adulthood knocks.
From what I saw, there’s a bit of overlap with other nostalgia-laden narrative games about teens growing up, such as studio Don’t Nod’s Life is Strange series or last year’s Lost Records: Bloom and Rage. But Mixtape avoids the plotty drama of those games in favor of lionizing the humble wonder of teens killing time. And it does it in style, with kinetic editing and needle drops that immerse players in the MTV-drenched lives of kids whose rebellious days are numbered. It’s tonally different, reflecting Galvatron’s memories of being an earnest teen, liking music and tossing out strong opinions.
«There’s a lot of stories about teenagers where they’re portrayed as very shy and not confident. And that’s not really my experience of being a teenager,» Galvatron said. «I was very confident and wrong about things and about how I felt about music.»
Galvatron’s earnest teenagehood was in Australia, but setting the game there might have been too close to home. Plus, his favorite music and culture came from America. Despite not coming to the US until he was 32, he’s watched America every single day of his life, he said. Seeing it in person is like coming to a theme park, or a fantasy land: «To people who live in Western cultures, America is Middle-earth,» Galvatron said.
The game is split into chapters, each patterned after a carefully-chosen song. They all come together in the titular mixtape, the swan song of a cherished friend group, one last rock-out to tunes that speak to the moment. It was those songs that drove the creation of the emotional sequencing of Mixtape, Galvatron told me. Whereas most games start development by creating a «vertical slice» that represents the core loop of the game, Beethoven & Dinosaur made «a real shitty version of the whole game» and swapped around the songs to see what different stories the configurations told.
«We would play with that soundtrack until it seemed to have this cinematic flow to it, like a really lovely narrative that chained these songs together,» Galvatron said. «Once we had that right, we could put the story and the characters in.»
Picking the songs was a delicate process to find the right tone (and to ensure variety, as Galvatron joked he kept wanting more Devo songs, which the team vetoed and limited him to one). There’s a pivotal moment in the game where the main character Rockford is betrayed by her friend, and despite digging up the saddest songs they could think of, none worked. So they flipped the emotions to the other extreme, trying tunes evoking over-the-top happiness like Stuck In The Middle With You, and went with songs from the artist BJ Miller from the 1960s, «and that seemed to make it just all the more devastating,» Galvatron said.
I saw parts of 4-5 song chapters out of what Galvatron told me will be a total of 26 or 27. But each felt like a sublime snippet (in Pixar parlance, a core memory) that the player gets to control, from an embellished shopping cart escape from the cops to a flailing first kiss of awkward tongues to rocking out in the car on the way to a party. It sounds mundane, but these delightful moments hearken to a time in everyone’s lives when the people and the songs around you elevated the simple into the unforgettable.
«We don’t have skill trees, we don’t have (gameplay) loops. We have moments where mechanics, music, dialogue, narrative all meet and hit these crescendos,» Galvatron said, and emphasized the importance of their brevity. «Get in, deliver the mechanic, make it beautiful, make it a great experience. Don’t overstay your welcome.»
It’s undeniable that Mixtape reaches back into the past to evoke a feeling of place and time, specifically this moment in the American 90s where music was blasting from cassette tapes and CDs. There’s a warmth to this equipment, Galvatron noted, and to the music it produces. Moreover, the tactility lends itself very well to touching, spinning and clicking motions on game controllers, giving players a real feel for the music they’re playing on screen.
Yet when I asked how he felt the game fit amid our current era of nostalgia — which media like Stranger Things have built IP empires upon with period-appropriate references, fashion and songs — Galvatron asserts that the game has a different aim than prompting viewers to remember specific songs, CD players and Tamagotchis. «What I want people to remember is when you defined yourself by the singles you liked, by art, and I think that’s something naive and sweet,» he said.
If the rest of the game meets the bar set by the demo I saw, players will be pretty awestruck by the polished, electric delivery of moments from scene to scene. Mixtape feels intentionally designed, likely meticulously storyboarded, to land moments with camera angles and timing that make you feel along for the ride.
Beethoven & Dinosaur’s strengths are leaning into the grandness of cinematics and music, Galvatron said. «That’s how I remember being a teenager,» he said, «[it’s] something theatrical and fast, and everything meant the end of the world or the start of the world.»
