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
