Spool Hole Reducer Screw

thingiverse

Yet another spool reducer for spools with a larger inner hole. Good to have for a spool holder with shorter distance and spools not fitting there very well. It has some cuts at the turning sides providing better grip when tightening and to loose the screw. And the inner diameter is good for spool holder bars having some bigger maximum diameter (here up to 40mm). The screw and bolt here should be good for spool holes with a diameter of 64 to 84 mm (or so) and a spool width up to 65 mm (or 75 mm longer version). Have fun!
