Filament clip with screw (Ender 3)

thingiverse

I redesigned it in Fusion 360 to give the threads looseness to print on Ender 3. I attached the Fusion 360 file so that it can be easily changed. Even with a full bobbin, it works well, thanks to the serration on the outside. I created a screw with the head a little bigger than the original to facilitate the tightening the first time.
