After a lot of requests, I finally made it — a W12 engine block fidget keychain!
Turn the flywheel and watch the pistons move inside the cylinders. The mechanism is designed to be satisfying to play with while also looking like a miniature mechanical engine.
Features:
Functional flywheel mechanism
Moving pistons
Prints completely without supports
Cylinder firing order is the same as on a real W12 engine
Designed as a compact keychain
asy to customize with different filament colors
Printing recommendations
The model can be printed without supports.
For the camshafts, I recommend using PETG. It provides better durability for the moving parts and should handle repeated use better. Important: I also recommend adding a small amount of lubricant to the camshafts during assembly. This will make the mechanism smoother and reduce friction between the moving parts.
If you print one, I'd love to see your make!
