Reverse Bowden Z-Tops and Spool holder

prusaprinters

Needed a way to mount my spool on the inside wall of my printer cabinet, and still give a usable filament path. So I drew up some parts to utilise a reverse Bowden setup, but with simple press fit holes for 4mm tubing to keep it light and simple. (Also did a matching non-bowden piece, cause OCD..) I used standard Capricorn tubing for the bowden, but any 4mm OD tube should work fine. Also needed to get a spool holder in position, so drew up a bracket to be able to use the standard plastic Prusa support tube. I wanted to be able to quickly remove the spools if needed (as the printers are on pullout trays) and the standard holder has a nice simple rotation locking mechanism. Held in place with normal chipboard screws.
