The Dutch company Archimedes invented a "power-generating rose", its full name is LIAM F1.

I get the idea and trying to do it with fusion 360, it is a toy, but still has the potential to develop into a real generator.

easy to print, no need to print support.

this is the material list:

684zz bearing x 2

608zz bearing x 1

m4 20mm screw x 2
