About this 3D model
We needed an adapter from our Scheppach planing machine (Dickenhobelmaschine in German) to a vacuum. On both sides the diameter gets tighter with 2 degrees skew. It is designed quite heavy because of the forces and vibration. Printing instructions I have printed it in extruder PETG, 80% infill, 0.2 mm layer, standing on the bigger hole, without supports, outer brim.
