Dremel 4000 threaded mount remix

I was looking for a way to mount a dremel 4000 onto solid surfaces as simply as possible and found this mounting solution for a cnc attachment. I've removed the angled tabs and the rounded back, and I've added a flat base with pretty flexible holes for screwing or bolting this onto anything.

This is the collar threaded part only; the original brace for the bottom of the dremel can be used from the original project that I remixed if needed.
