Spare Filament Roller with Buffer

This is a two spool filament roller with a two chamber buffer box underneath for a small footprint. I use a dry box with five filament rolls leading through PTFE up to a buffer box, then through the bottom of the workbench and up to the MMU2S. This means changing filament colors is a bit time consuming, so this Spare Filament Roller provides an easy way to add a color or a specific roll for a specific print.

Parts list:
All printed items (print two of the Diverters)
Two (2) PTFE tubes, 11” long
Two (2) PTFE tubes, long enough to get to your printer from the box
Four (4) PC4-M6 compression fittings
5mm (#9) drill bit
M6x1.0 tapping tool
