refill spool Masterspool

This is a design I made to re-use my empty filament spools instead of printing a refill spool.
I have now made a couple dozen of these and are working great. the spool holder opening for this is 42.5mm ( it fits over the creality and geeetech spool holder nut easily )this should fit any spool with a center hole that measures 54mm and is a bout 65mm wide.
