Dobot Magician Tabletop Base Holder

One of the biggest problems with the Dobot Magician is that due to it's low weight it tends to be easily bumped or moved about by a wrong turn in the programming chain, and repositioning is tedious and often unsuccesful.

The holder bolts on to a tabletop/work surface using 3.5mm diameter bolts. Base is 5mm thick. Holes are countersunk for 6mm head. Lateral clearance after insertion is about 1-2mm, depending on printer precision. Needs to be side shimmed to be completely rigid - card stock doe
