IKEA Stuva enclosure porthole pass-through (with swivel filament guide)

This is a swivel filament pass through I made for my Ikea Stuva printer enclosure. I'm currently using it with a direct drive Greg's Wade extruder with a J-Head Mk V-BV. In order to use more abrasive filaments (and plated nozzles) I'll be trying out a Bowden extruder with a E3D V6 hotend soon.


Diameter of center hole to drill for the porthole is 38mm (1.5 inches)

Thickness of the cabinet is 30mm (1.2 inches)
