Adjustable Filament Holder Tensioner and Tangle Guard

thingiverse

I wanted something simpler than an auto-rewinder to stop my filament holder from rolling back. This was a simple solution that just adds a little bit of pressure on the spool and has the added benefit of stopping tangles since it also acts as a guard. I stuck a couple small Chair Floor Protectors from the dollar store on to the guard and now the spool unwinds silently and controlled. You can adjust the pressure by moving the bar closer or further using the elongated hole that it attaches to the filament spool holder.
