Update on Spindle Gear: Revised version works great but I got a batch of inferior prints from JawsTech.com so I won’t be selling any due to having to print them at a higher cost at Shapeways.com. I could only afford the 3 that I need so if you need it just message me for the 3D model. I know the Shapeways.com prints will be solid. I’m still amazed that I made a part!
