Prusa i3 MK2 Spool Holder

I absolutely hated the provided spool holders that came with the Prusa i3 MK2 so decided to spice up the aesthetics and make it a bit more functional with a crossbar to hold the filament. All spool sizes should be compatible.

I wanted to test captive nuts while printing so the arms connect to the cylinders via embedded M3 nuts and secured using 15mm M3 bolts. I've provided a guide on how to pause the print to add the nuts.

I've also provided a combined .stl for those that don't want to use
