Vacuum Sucker for Drilling - 30-35 mm Smooth Barrel
thingiverse
I looked at Petclaud's design and decided to create my own with some alterations. :) + More room between drill and vacuum tube (~42 mm) + Easier printing with supports optional + Supports at least 30-35 mm smooth vacuum tubes + Better suction and protection of the wall with optional sealing + Smooth edges :( - Larger - Heavier - Longer print time - More material used The angle between wall and vacuum tube is 45° and the hole for the drill bit has a diameter of 20 mm. I designed this in Autodesk Inventor Professional 2019, the .ipt file is available.
