3d printable Sieg x2 mini mill belt drive conversion by death4u

Last crawled date: 3 years, 3 months ago

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.
