Filament guide throught the cabinet wall

This is designed for my printers cabinet. You can drill a hole and put this giude to cleanly inserrt filament to the cabinet. wall thickness 1-15 mm, but its easy to create new longer screw.

You can scale it down 50% and it still will work just fine.

You can use two "nuts" and a pipe-screw to mount it, or use one nut, mount it to the wall by some 3mm metal-screws and insert pipe-screw.
