AO-101 Spool Holder

This is a spool holder that i made just for fun on tinkercad. It replaces the left back bracket on the Lulzbot AO-101. It does work, and makes switching filament easy for me.

UPDATE:
I had an idea to make the washers triangular so that they can both be printed at the same time ON the AO-101.
