Good 3D printed Bitcoin accessories should do more than put a Bitcoin logo on a random piece of plastic. They should solve a real problem, protect expensive hardware, organize a mining setup, or become the one object on a desk that starts a conversation every time somebody sees it.
That is what CryptoCloaks has been building since 2017. We design and print Bitcoin art, home-mining gear, self-custody tools, hardware-wallet cases, and useful everyday pieces in Colorado. Some products are practical. Some are completely unnecessary in the best possible way. The Original Bitcoin Grenade manages to be both.
This guide explains the main categories, what each accessory actually does, and which products make sense for your setup. Prices below were verified on July 27, 2026 and can change.

Bitcoin Art That Does Not Look Generic
The Original Bitcoin Grenade is where this category starts. CryptoCloaks created it in 2020 for the CryptoEcon conference in Hanoi. It has since become a recognizable piece of Bitcoin culture instead of another anonymous logo product.
The current Gen 3 version is fully 3D printed, available in more than 25 colors, and built with a removable carbon-fiber-infused top. The body is hollow, so it can hold an Opendime, a note, or another small object. It is still a novelty art piece, not a real grenade, but it has an actual use beyond sitting on a shelf.
At $25, the standard grenade is the best place to start. The BIG BOI Bitcoin Grenade takes the same idea to approximately five inches wide by nine inches tall. It costs $79.99 and works better as a shop, conference, office, or studio centerpiece.
Smaller versions carry the same design into inexpensive gifts. The Bitcoin Grenade Squish Key Chain is $4.99, while the Bitcoin Grenade Magnet is $1.99. Those are easy add-ons when the full-size version is more grenade than the situation requires.
3D Printed Bitcoin Mining Accessories
Home miners are exposed boards, fans, cables, and hot air until somebody designs the missing physical pieces around them. This is where 3D printing is useful. A product can be built around the exact board outline, port locations, fan size, and duct opening without requiring an expensive injection mold.
BitAxe stands and cases
The single BitAxe Stand costs $7 and holds one supported miner upright. It keeps the board from lying loose on a desk while leaving the display and ports accessible. Double and triple versions organize multiple boards in one base.
If you are deciding between them, the single vs double vs triple BitAxe stand comparison covers current capacity, pricing, compatibility, color zones, and placement tradeoffs. Buy for the number of miners you actually expect to run. One miner does not need a three-miner rack, and three separate miners do not always need to be locked into one cluster.
Avalon Q exhaust control
The Canaan Avalon Q Exhaust Shroud solves a different problem: heat. It attaches to the miner’s exhaust and connects it to standard 6-inch or 8-inch flexible duct. That lets you route hot air toward a window, another room, or a space where the heat is useful.
The shroud is printed in PETG for better heat resistance than basic decorative PLA. It is a $25 accessory designed around the Avalon Q rather than a generic reducer that almost fits. The complete Avalon Q exhaust shroud guide explains duct sizing and placement in more detail.
A stand or shroud does not change the miner’s electrical requirements. It organizes hardware and manages airflow. Keep every miner in an open area, follow the manufacturer’s power guidance, and do not treat a printed part as a substitute for electrical safety.
Self-Custody and Hardware-Wallet Accessories
The most useful 3D printed Bitcoin accessories are often alignment tools and fitted cases. They do not replace the security device or backup material. They make those systems easier to assemble, protect, and use correctly.
Blockmit Washer Jigs
The Blockmit Washer Jigs hold a metal washer and help position each stamped letter. Two jigs currently cost $5. The jig is not the backup itself. The stamped metal washers are the durable record, while the printed tool keeps the lettering organized and readable.
You will still need stainless-steel washers, a hammer, a solid work surface, and a 3 mm letter-punch kit. Never stamp a real seed phrase where cameras, microphones, cloud-connected notes, or other people can capture it. The metal seed phrase stamping guide covers the process and the privacy precautions.

Coldcard Q cases
The Coldcard Q Solid Color Case is $7.99 and wraps the signing device in a fitted outer shell. It helps prevent cosmetic damage and makes a specific device easy to identify when more than one is stored securely.
A case does not make poor key management safe. It protects the device’s exterior. Your PIN, backups, passphrases, firmware verification, and physical storage remain your responsibility. Read the Coldcard Q case guide if you want a deeper look at fit and case choices.
SeedSigner cases
SeedSigner is a do-it-yourself signing-device project assembled from separate hardware. A fitted enclosure turns those parts into one usable handheld unit. The SeedSigner Orange Surf Case is currently $9.99. As with every SeedSigner enclosure, confirm that the case matches your exact screen, camera, and board configuration before ordering.
Useful Bitcoin Gear for Desks, Homes, Music, and Golf
Not every Bitcoin accessory needs to secure keys or cool a miner. Small printed products work well when the shape, color, and layer texture are part of the point.
- Bitcoin Coaster x2: Two PLA coasters for $12.99.
- Bitcoin Guitar Picks: A ten-pack of playable picks for $4.99.
- Bitcoin Golf Tees: A five-pack for $6.99.
- Bitcoin B US Outlet Cover: A $4.99 replacement cover for a small permanent Bitcoin detail in a room.
- Bitcoin Grenade Magnet: A $1.99 version of the original design for a refrigerator, cabinet, or tool chest.
These are good entry points because they are inexpensive, useful, and easy to gift. They also make sense as cart add-ons after the main CryptoCloaks product rather than pretending a tiny magnet is the center of the Bitcoin universe.
How CryptoCloaks Makes 3D Printed Bitcoin Accessories
Every design starts with the thing it needs to fit or the problem it needs to solve. For a miner stand, that means board dimensions, screen visibility, cable access, fan clearance, and stability. For a hardware-wallet case, it means button access, port clearance, and a secure fit. For the Bitcoin Grenade, it means preserving the original silhouette while making the top removable and the body useful.
The parts are produced layer by layer on the CryptoCloaks printer farm in Colorado. Printing in small batches lets us offer far more color combinations than a conventional molded product and revise designs when hardware changes. It also means the layer lines are part of the finished object. These are printed parts, not injection-molded parts pretending otherwise.
Material depends on the job. Decorative and general-use pieces often use PLA. Products near sustained miner exhaust may use PETG for additional temperature resistance. Product pages identify the important material and compatibility details, so check the specific listing instead of assuming every printed item behaves the same way.
Minor surface variation can happen with any printed part. That does not mean a poor fit is acceptable. Functional products should still mount securely, expose the correct controls and ports, and do the job described on the product page.
How to Choose the Right Accessory
Start with the exact hardware model
Do not buy a case or stand because the product names sound close. Match the exact BitAxe board, Coldcard model, SeedSigner build, miner, fan, or duct size. Small revisions can move a port or change an enclosure dimension enough to matter.
Separate protection from security
A printed hardware-wallet case protects the exterior. A Blockmit jig helps create a backup. Neither replaces good self-custody practices. Know what the product does and what it does not do.
Choose material for the environment
A coaster and an exhaust adapter do not live in the same conditions. Pay attention to heat, direct sunlight, impact, and mounting stress. If the product sits near a miner, use the product specifically designed for that miner and temperature range.
Buy the main product first
If you came for the Bitcoin Grenade, start with the grenade. If you need to manage Avalon Q exhaust, start with the shroud. Small accessories can complete an order, but the correct primary product should solve the reason you came to the shop.
Frequently Asked Questions
What are 3D printed Bitcoin accessories?
They are printed physical products designed for Bitcoin art, mining hardware, signing devices, seed phrase backups, desks, homes, and hobbies. The useful versions are built around a specific purpose or exact device rather than adding a logo to a generic object.
What is the best 3D printed Bitcoin accessory to start with?
The Original Bitcoin Grenade is the signature CryptoCloaks piece and the best general starting point. For a practical purchase, choose the stand, case, shroud, or backup tool that matches hardware you already own.
Is the Bitcoin Grenade real?
No. It is a 3D printed novelty art piece and storage object. It does not contain explosives and cannot function as a real grenade.
Are 3D printed hardware-wallet cases secure?
A fitted case can protect the outside of a signing device, but it does not improve the cryptographic security of the wallet. Buy the correct case, inspect the fit, and continue following the device manufacturer’s security instructions.
Are the products made in the United States?
CryptoCloaks designs, prints, packs, and ships its products from Colorado.
Can I choose custom colors?
Many CryptoCloaks products have live color choices. The available zones and colors vary by product, so use the selectors on the individual listing.
Can I pay with Bitcoin?
Yes. CryptoCloaks accepts Bitcoin, and traditional payment methods are available too.
Start with the Piece Your Setup Actually Needs
The right accessory is obvious once the problem is clear. Protect the hardware you own. Route the heat your miner produces. Build a backup you can recover. Or put the Original Bitcoin Grenade on the desk and accept that everyone is going to ask about it.
