I made this to create a PTFE tube path for my filament from the top of my LACK enclosure. This is threaded to fit a PC4-M10 PTFE Connecter.
I printed in rPETG from 3D Fuel. PLA would be fine too.
You will need to cut a hole in the table (center is hollow) 10mm would work nicely. Tube size is 9.5mm. It doesn't need to be exact as the flange is 30mm dia and would hide some mistakes/marks.
The author remixed this model.
