What am I looking at?
These are mechanical bead puzzles. The goal is to group the beads by color. There are two types of moves:
- Sliding an entire row of beads through its track
- Rotating the colored “rotor” — the circular piece(s) held within the black body
All puzzles ship in the solved state. Beyond the standard solution, there are also many interesting alternate patterns to discover, such as alternating colors or symmetric arrangements.
The Pretzel is the only model that includes a solution diagram, printed on the back of the packaging. Even so, it also has several interesting symmetric alternate solutions to explore.

Aren't 3D prints fragile, low quality trinkets that break the first time you drop them?
A lot of people’s experience with 3D printing comes from mass-produced novelty toys — lightweight prints made quickly and cheaply, often with low internal density and minimal durability.
Our products are different. They are made with much higher density and finer layer heights to improve strength, precision, and surface quality. They take longer to produce and use more material, but that extra time is what gives them their solid feel and durability.
They are designed for 3D printing from the ground up, taking advantage of all the benefits over injection molding (like unrestricted wall thickness, and overhanging geometry).
Check out this video for some durability testing, featuring timed subtitles and drumming!
Are these for kids?
While some of the easier models may be within the intellectual capabilities of kids as young as 10, these products have not gone through the mandatory testing most countries need for kid's toy safety. As of right now all products sold online are strictly intended for 14 years or older.
At retail locations in some regions, other age guidance may apply - see the printed information on the packaging.
I need help solving it!

How do I not wreck it?
We do thorough durability testing by dropping, hammering and generally abusing each different puzzle model - they are designed from the ground up to be tough!
The 3D printed parts are made of PLA, a durable plant based thermoplastic. To keep your puzzle in good condition:
- Clean gently with a damp cloth. Do not use solvents or harsh cleaners.
- Avoid high temperatures — PLA can begin to soften around 60°C (140°F).
- Do not store in direct sunlight for long periods, as UV exposure can gradually degrade most plastics, including PLA.
I got cookie crumbs in the tracks
These puzzles are designed to be disassembled and reassembled, but it can be a bit fiddly the first time — and small parts (like the balls and springs) can be easy to lose if you’re not careful.
If there's something in the tracks, start with a soft brush, compressed air, or a small pick to gently clean out them out.
If you need to fully disassemble the puzzle:
- Work over a tray or bowl to catch any loose pieces
- The base is removed by turning it counter-clockwise
- Take note of which colors are used internally before emptying the tracks
- Apply light sideways pressure to the rotor while removing the base to prevent it from pulling the rotor out (they are magnetically attracted)
- If the rotor comes out with the base, the balls will come out of the tracks. Use a bowl or tray.
- It helps to keep the puzzle upside down during disassembly and reassembly
- Recording the process can make reassembly much easier later
Take your time — reassembly is straightforward once you’ve seen the internal layout once.
