Filament Hole Protector 12.5mm

When I moved my 3D printer into a cabinet, the filament reels were relocated to the top of the new cabinet. The filament spools through the cabinet roof into the printer.

The cabinet hole needed to pass through three 1.75mm filaments each shrouded by a PTFE tube.  The inside hole diameter chosen was 12.5mm.  The outside hole diameter is 20mm.

The cabinet is metal with 1mm panels and has had a 20mm hole drilled through the metal for the filament and protector to pass through. This 3D printed model provides a smooth path through the cabinet roof hole. The model has two parts, a smooth upper section and held in-place by a M20 3D printed nut.

My print is made in PETG 1.75mm 3DFillies black filament, with 0.2mm layer height and 100% infill on a PRUSA I3 MK3S printer.

I hope you can find this print useful, too.
