Filament tube holder for Prusa CORE One with MMU3

This small loop attaches to the roof of the CORE One printing chamber and holds a 4mm PTFE tube. The screw of the MMU may be used to attach it.

I made this to guide the side input tube up to the MMU tube, which are then connected with a Y-splitter. This way you don't have to switch tubes at the printhead when switching from the side input to the MMU.

Printing

Use a filament that can withstand the expected temperature inside your printing chamber. I used ASA, PETG should be sufficient in most cases, and I would not recommend PLA.

Layer height: 0.15mm
Infill: 100%
Supports: No

Installation

(Re-)use one of the screws that attach the MMU to the CORE One (see photo).
