Dremel 82xx Drill Press Adapter

An adapter ring to use a Dremel in a normal drill press stand.
 

I made 2 versions, for both the outer diameter of the ring & collar is parametric.

For printers that lack accuracy, especially for holes/inner threads, I added a "ThreadDiaScaleFactor" parameter to compensate, the pitch of the thread is not affected.
For most printers a scale factor between 0.98 & 1.06 does the job.

The adapters in the print profile are Ø38mm

The thread is 3/4-12 UN (not quite M19x2).
