A1 Spool Tensioner

When my spool start running low on filament the vibrations of the printer make the spool bounce up and down, which causes the spool to unwind. I've made this model to solve this issue by gently pushing on the spool, creating enough friction to negate the spool unwinding due to the vibrations of the printer. The pieces attach easily to the printer by clipping to the top bar, and locking in place with a dovetail. I hope you enjoy this model and I hope it fixes any issues you may have.
