Filament sensor cover Prusa i3 MK3S reverse bowden 6/4mm tube

Filament Sensor Cover for the Prusa i3 MK3S which is adapted to accept a 'reverse bowden tube' to a filament dry box.

You have to press fit a small piece of 6mm Festo tube in, see photo. The Festo tube has a inner diameter of 4mm. After that it accepts normal 4mm bowden tube. I do like this solution over a coupling, because it provides easier access when changing filament.

How I Designed This

It is a remix of the Filament Sensor Cover version R4 for the Prusa i3 MK3S as found on:
www.prusa3d.com/downloads/others/Original-Prusa-i3-MK3S.zip.

In ThinkerCAD I just added a cylinder on top of the filament feeder opening. Lenght 12 mm, outer diameter 10mm, inner diameter 5.8mm. Thats all.
