Mini Rotary Tool

This is a simple rotary tool I decided to build after finding a motor that came with a tool chuck. It's really easy to make, and does a great job cutting, sanding, and polishing (sort of) 3d prints.

When printing, make sure the resolution is high enough for the threads to work. My printer allows threads to work up to 0.15mm layer heights, but no thicker. Remember, different printers have different tolerances.
