Top Mounted Spool Holder

This is a top rear-mounted spool holder for the Kobra S1. I found that side-mounted spool holders didn't work well for my spool of TPU because it would pull sideways without unrolling from the spool. I can't use the built-in rear spool holder because I have a poop chute there and it's hard to reach anyway. So I needed a spool holder at the top of the printer. This design takes inspiration from this model but includes a built-in spindle for the spool to sit on, uses less filament, and is adapted to Kobra S1 models that have the third screw hole pushed further to the right (might be a newer design). Simply print and screw in place using the existing screws on the back of the printer.
