This is a small filament buffer that mounts directly to the Pico MMU and supports a maximum of 140mm rewind.
I made this small buffer for my mmu setup and the main goal was to save as much table space as possible and also easy accessibility and handling. The unique form factor of the Pico MMU directly encourages this. The best place to mount it seemed to be on the monitor stand. It was necessary to place the filament spools as close to the mmu as possible. Even though I have the filament hub positioned on the toolhead, the short distance of the spools from the mmu could not compensate for the backward movement when changing filament and loosened the spool winding.
It is designed as a slot system so can be used for both 3 lane and 4 lane Pico MMU.

Make sure your printer is properly calibrated, especially for printing bridges and overhangs. Some slight post processing of the filament path might be needed.
To get started, just print the parts for 1 lane (buffer_body, wheel, spacer_608 and side_right) and join them with the M3 bolts and nuts to test that it works for your setup.
