Filament Spool Hub
Description
I created this spool hub for a problem with salvaging 3D Systems Cube cartridges. Their cardboard spools don't hold up well outside the case. This solves the issue by using only parts A and B. Part C was added to make this elegant little emergency spool. This little spool holds about 1/4lb of filament when using CD's or DVD's as flanges. You can cut flanges from cardboard or any medium you can fabricate into useful flanges. The center diameter is about 2". The hub's core diameter will be 2-3/4" when using the center spacer.
