An alternate solution to MMU2S buffer. Easy to locate away from filament and easy to load.
Somewhat of a remix (or at least inspired by) https://www.thingiverse.com/thing:3529934 from jgillick
EDIT: Loop the filament around the wheel twice before feeding to MMU2.
Print instructions
Print everything flat. 1 base, 5 sets of verticals, 5 wheels.
Insert a 508 bearing into each wheel. Assemble using M3 screws.
Use 4mm OD PTFE to the MMU2 as well as out to the filament.
I use a piece of double-sided tape (3M command tape/tabs) to hold it to the tabletop.
I printed in PETG, but PLA should be fine. Used .4mm nozzle. Printed base at .2mm for quality/clearance for PTFE tubes. Verticals and wheels don't really matter on layer height.
