Zebra ribbon core

This is a ribbon core for most Zebra desktop 4 inch thermal transfer printers. I've tested it with GK420t and GC420t printers.

Most thermal transfer printers come with a cardboard piece that rolls up the used transfer ribbon, but if you lose the piece or need to change ribbon before finishing the entire roll, it's difficult to find a replacement online.

Fusion 360 source file is included for tinkering. (even though it's a really simple design)
