This is a belt drive conversion that can be almost completely 3d printed. My mill broke and I wanted to make a printable belt drive. It started out as only a temporary fix, but I've been using it for several months without problems. This conversion doesn't have a spindle lock yet. I've been using an er20 collet and haven't needed the spindle lock. There is also no guard yet. The Fusion 360 files have been included.
