Tri Hex Spool

This is my first attempt at designing a filament spool. It has a same external dimensions as the Bambu spool so it fits in the AMS and AMS lite. It also works with the Bambu cardboard refills. It has holes around the center for the filament to be inserted into for re-spooling, and holes along the edge to thread it through in case you don't want to use a filament clip to keep it from unwinding. I would probably recommend using a heat resistant filament if you plan on using it in a dryer. But
