Replicator 2 No Squeek Super Cool Spool Holder Upgrade
by ajf, published
This is a replacement spool holder for the MakerBot Replicator 2 (or 2X). This spool holder pays out filament super smoothly and solves the plastic on plastic squeek/screech the original spool holder exhibits (as the MakerBot tugs on the filament during print jobs).
This spool holder can be easily adapted to use MatterHacker spools, etc.
