Spool Roller with metal hardware

I got tired of trying to use plastic threads to do this as multiples had broken on me. This is setup to use a 6-7" piece of 3/8 rod, 2) 3/8 nuts, and 2) 3/8 washers. Hang your broken spool on the back or side of your printer or another roller that uses the center and chuck this setup in a drill.
