Dremel 4000 tool holder for MPCNC

Yet another wildly experimental early prototype tool holder for MPCNC. Probably also works with most other Dremel models that have a 3/4-12 UNC collar. Just so you know, this is for the US, not the IE version.

Ran a test print at 10% infill with junk PLA because I didn't have 12 hours to print it solid. The fit is arguably perfect. Nice job mstrperson on the 3D printed threads.
