Fantastic. Well-executed!

I just printed it and I love it! What is the purpose of the bar.stl?
@GuilleBrossi_1302816 Hello,
this is an anti-rotation feature to keep the holder aligned with the profile.
nice design, but why not just slide the spool back to the extruder?
@SonicBoom_156790 The goal is to pull the filament straight into the extruder.
