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.

OpenAI’s Revenue and Expansion Projections Miss Targets Amid IPO Push: Report
OpenAI’s revenue and growth projections fell short of internal targets, raising concerns about its ability to fund massive data center investments ahead of its planned IPO.
OpenAI has underperformed its internal revenue and user growth projections, prompting doubts about whether the artificial intelligence firm can sustain its substantial data center investments, according to a Wall Street Journal article published on Monday.
Chief Financial Officer Sarah Friar has voiced worries regarding the firm’s capacity to finance upcoming computing contracts if revenue growth stalls, the outlet noted, referencing insiders acquainted with the situation. Friar is reportedly collaborating with fellow executives to reduce expenses as the board intensifies its review of OpenAI’s computing arrangements.
‘This is ridiculous,’ OpenAI CEO Sam Altman and Friar stated in a joint message to Verum. ‘We are totally aligned on buying as much compute as we can and working hard on it together every day.’
Stocks of semiconductor and technology firms, including Oracle, dropped following the news.
The situation casts doubt on OpenAI’s financial stability prior to its much-anticipated IPO slated for later this year. Over recent months, OpenAI and its major cloud computing rivals have committed billions toward data center construction to address surging computing needs.
Several of these agreements are directly linked to OpenAI. Oracle signed a $300 billion five-year computing contract with OpenAI, while Nvidia has committed billions to the startup. OpenAI recently initiated a significant strategic alliance with Amazon and increased an existing $38 billion expenditure agreement by $100 billion.
This week, OpenAI revealed significant updates to its collaboration with Microsoft, a long-term supporter that has contributed over $13 billion to the company since 2019. Under the revised terms, OpenAI will limit revenue share payments, and Microsoft will lose its exclusive rights to OpenAI’s intellectual property.

OpenAI Expands Cloud Access by Partnering with AWS Following Microsoft Deal Shift
OpenAI is expanding its cloud strategy by making its AI models available on Amazon Web Services following a shift in its Microsoft partnership, enabling broader enterprise access through Amazon Bedrock.
Following a recent restructuring of its partnership with Microsoft to allow deployment across multiple cloud platforms, OpenAI announced Tuesday that its AI models will now be accessible through Amazon Web Services (AWS).
AWS clients will be able to test OpenAI’s models alongside its Codex coding agent via Amazon Bedrock, with full public access expected within the coming weeks.
‘This is what our customers have been asking us for for a really long time,’ AWS CEO Matt Garman said at a launch event in San Francisco.
Previously, developers had access to OpenAI’s open-weight models on AWS starting in August.
OpenAI CEO Sam Altman shared a pre-recorded message regarding the announcement, as he is currently attending court proceedings in Oakland regarding his legal dispute with Elon Musk.
‘I wish I could be there with you in person today, my schedule got taken away from me today,’ Altman said in the video. ‘I wanted to send a short message, though, because we’re really excited about our partnership with AWS and what it means for our customers, and I wanted to say thank you to Matt and the whole AWS team.’
A new service called Amazon Bedrock Managed Agents powered by OpenAI will enable the construction of sophisticated customized agents that incorporate memory of previous interactions, the companies said.
Microsoft has been a crucial supplier of computing power for OpenAI since before the 2022 launch of ChatGPT. Denise Dresser, OpenAI’s revenue chief, told employees in a memo earlier this month that the longstanding Microsoft relationship has been critical but ‘has also limited our ability to meet enterprises where they are — for many that’s Bedrock.’
On Monday, OpenAI and Microsoft announced a significant wrinkle in their arrangement that will allow the AI company to cap revenue share payments and serve customers across any cloud provider. Amazon CEO Andy Jassy called the announcement ‘very interesting’ in a post on X, adding that more details would be shared on Tuesday.
OpenAI and Amazon have been getting closer in other ways.
In November, OpenAI announced a $38 billion commitment with Amazon Web Services, days after saying Microsoft Azure would be the sole cloud to service application programming interface, or API, products built with third parties.
Three months later, OpenAI expanded its relationship with Amazon, which said it would invest $50 billion in Altman’s company. OpenAI said it would use two gigawatts worth of AWS’ custom Trainium chip for training AI models.
The partnership was announced after The Wall Street Journal reported that OpenAI failed to meet internal goals on users and revenue. Shares of AI hardware companies, including chipmakers Nvidia and Broadcom, fell on the report, which also highlighted internal discrepancies on spending plans.
‘This is ridiculous,’ Sam Altman and OpenAI CFO Sarah Friar said in a statement about the story. ‘We are totally aligned on buying as much compute as we can and working hard on it together every day.’
