spool holder

Bambu lab filament spool holder, designed for multiple rolls of filament storage or attach 4mm tubing to supply to the printer for multi colour changes with out needing to remove the spool. basically a manual AMS. can be 2 deep and stack a third on top with the top locators. the feed holes at the bottom fits 4 mm hose very snug. either use a 4 into 1 adaptor or 3 free inputs on my A1 mini, on colour changes I just manually retract the filament enough to clear the next colour to be fed in.
