Super Low Profile Spool Holder for MK3S+

I could not find a spool holder that was low enough to clear my cabinets, so I remade one based on the great design that I found here. The arm length is a bit shorter than the factory arm, and lowers the overall height by about 2.7 inches. Print using supports touching build plate only. I printed at 20% infill, but that was probably overkill as 15% should be plenty strong.
