Designed to hold a rotary tool in a bench vice or on a surface to keep the tool stationary so you can manipulate the workpiece. Verified to work with Dremel and Chicago Electric Tool (Harbor Freight) brands.

Printing: No supports needed. Print with largest flat surface down as shown. Higher infill is not required unless you really want to apply a lot of clamp force to hold the fixture in place. I did 25% just to give me a little more safety factor before I accidentally crack it in a vice.

Rafts are not required but I often struggle with bed adhesion so I just raft everything by default
