Reverse Bowden Tap

My first “thing”; a 360 degree adjustable and stackable reverse bowden system designed for my Prusa MK3s frame. It swivels and looks like a tap, so I'm calling it the "Reverse Bowden Tap"

Design

I designed this for my custom dehydrator dry box which can hold 3 spools. I wanted something that could hold my filament and allow for easy switching without needing to back the filament out and this led to my stacking concept.

You can extend this design further if you like, but I have also provided bolt lengths to accommodate for stacking 3 or 2 Bowden tap arms.



BOM
You just need 2 x PC4-M6 and a length of 4mm OD PTFE tube per arm.

Versions

There are two version of the tap arms, standard and short body. The short body might be preferred in a stacked scenario. There are also two versions of the base, one inserts into hex fitting on either of the stock Prusa MK3 Z Axis tops. The other uses a customised Z
