Bambu Lab Spool Adapter for Protopasta Spools

prusaprinters

<p>Each spool needs 2 rings. Tear the cardboard sides off the original protopasta spool and insert the adapter into the center of the spool. I added a dab of glue where the adapter touches the cardboard center to keep the spool from rotating. The adapter has a notch to line up with the key on the Bambu reusable spools, so make sure that side of the adapter is facing out.</p><p>&nbsp;</p><p>Update: I have added an adapter for the Protopasta 500g rolls. The original adapter works for the 1kg rolls. The 500g rolls are narrower and have a larger diameter cardboard spool, that's why the adapter is so large. I printed mine with just 2 walls and 10-15% infill to try to cut down on filament usage a little bit.</p><p>&nbsp;</p><p>I only uploaded a .step file because that has been what I have been using on my X1. If you need an .stl let me know.</p>
