Intended to match the size of the proxxon micromot mount ( 20mm) so that the Lidl drill can be used in a drill press holder made for a proxxon.
A quick fix as my proxxon has a chuck and I haven't ordered collets yet. The parkside has aluminum collets... Maybe put off ordering proxxon collects.
A bit tight but fits. OpenSCAD available if someone would like to adjust it. It needs the ISO Thread Library
Printing with something that is not brittle, I used PETG.
Layer height, 0.1mm to 0.15mm so there is enough detail in the threads.
