cubic trisection
myminifactory
I bet most of you know this puzzle, but actually (for me at least) designing this was pretty challenging. With Fusion 360 being one of the top design software tools, I'm hoping that the original source file will provide some help, plus the usual STLs are available. By the way, I left a 0.3 mm clearance/tolerance gap - feel free to increase or decrease it in Fusion if you need to. Personally, I used a tighter gap because my printer is very well-calibrated, but the STL has a bigger gap to make it more accessible to a wider range of users. As always, you can adjust it in Fusion. P.S. Please give me extra credit for this - I'm only 14!
