Filamentguide for heavy duty shelf

This coupling part is used to safely guide the filament for the MMU2S from one level to the next, where the printer is located. The holes are 9.5mm in diameter and so PC4 M10 couplings fit perfectly. The part is intended for a material thickness of 5mm. The top rim is 1x1mm. The hole that needs to be cut is 15cm long and 3cm wide. Can be easily realized with a Forstner bit and a jigsaw.
