I HOPE TO TEST IT NEXT WEEKEND ON GulaschProgrammierNacht.


  • use a third M5 hole that already exists in the Thing-o-Matic to stabilize the adapter against backlash in milling
  • grip the edge of the toolhead-platform for added stability

This should allow me to do the PCB milling much faster without loosing precision to backlash.

I made this adapter, so I could reuse my very stable Dremel milling-head on the new Thing-O-Matic.
Any RepMan-toolhead should fit with this adapter.

I oriented the part, so that it prints well on a Thing-O-Matic.


I designed the grip for the edge of the toolhead-platform 1mm smaller then the DXF-files to accomodate for inprecise printing.
