This gear train was designed from scratch as a gear desk toy. If cut properly, minimal drilling should be required to use two M4 bolts and washers (or 8-32) and thread them into the gear train base.
If you've got similar materials on hand, use the provided g-code to cut your own. If not, you can still get the 3D model and put it through CAM yourself. Created to be CNC'd; milled on the Sienci Mill One.
Material: 6mm acrylic
End Mill: 2-flute, 1/8″ flat end
Cutting Time: 14 minutes
