About this 3D model

The original version was quite chunky, and required you to disassemble the spool to use it the firs time… I don't have any spools I can do this to yet, so I needed to improvise. I also didn't have any M4 screws… The other requirement I needed was to be able to level these attached when respooling from another filament spool. This version allows you to use M3x8 countersunk screws, to give an almost flush feel… Not sure if it will work in the full-size AMS. I've also tested it with M3x8 self tapping, and M3x8 machine screws. These stick out a little more. The best thing about this is that it captures the filament on the inside of the spool - no poking filament through a hole or outside the edge, no bending or snapping. It's also a really quick print and using a tiny amount of filament.
