Endstop for Filler filament holder

thingiverse

I had issues with spools of certain shapes climbing off the end of the Filler spool holder and falling off. So I designed this piece to prevent that from happening. It simply snaps on from below, and fits the end snugly enough that a wandering spool will be held in place. I printed this standing upright to make sure the force applied to the arms that need to bend slightly as it is snapped into place does not align with the layer lines. This requires supports, but they were very easy to remove. I printed it in PLA, but it was still flexible enough to not break as it was snapped into place from below. Also comes off easily by bending the fastening arms slightly outwards, so it is simple to take on and off when changing spools.
