Here’s a render of a butterfly drive I’ve been designing for fun and Solidworks practice.
-Structure is laser-cut .25" birch plywood
-Only other custom components are 3d-printed spacers and axles turned from hex shaft.
-Currently weighs 30.5 lbs.
-Geared for 5.7 fps on Colson wheels and 11.5 fps on omni wheels (adjusted).
Questions or suggestions are welcome.
