THIS IS PART OF AN OVERALL Lack Enclosure design: https://www.thingiverse.com/thing:3129929
This is take two on the Original PRUSA i3 MK3/MK2.5 MMUv2 Backfeed situation for those that are having issues with alternate mounting as I was.
This mount to attaches to the SPANNERHANDS Spool System spool holders.
3 x M3x10mm/ per Backfeed device or spool.
2 x 4mm M10 Festo fitting.
1 x 220mm 4/2mm PTFE Tubing for between spool holder and Backfeed device.
Assemble and ensure 150mm between spools to ensure kinks don't happen between spools.
I have staggered my five which is sufficient.
Once assembled there should be almost no friction on rotating parts, clean as needed if not.
