Universal Spool Holder - No Tools Needed

This is an adjustable spool holder for your 3d printer (Ender 3 or Ender 3 clone, like the Voxelab Aquilla). The stock spool holder on these printers is just a too-small tube. It does the trick but allows the filament spool to rock back and forth and feed filament to the print head in "spurts".
