Description
Full assembly :
- 3 short rods
- 3 long rods
- 2 bases
Additional material:
- 1.5mm (brass) wire for the rotation. Or drill over it and use 1.75mm filament
- 3x3xHoweverLongYouWant (carbon) rods
Sory the images don't match, they are from a previous overwritten version.
I tried to refine the design as much as possible to make it easily understandable, so you can use it for your onw designs.
Design note : the angle between the 2 faces is twice the angle between a face and the face to centerline angle, just like 2 rotating balls
