Wall-Mounted Spool Holder

I made this when I had an Anycubic Kobra Neo for a bit, but printed it on my Ender 3 S1. It uses the stock spool holder but I expect that to be relatively similar to anything that comes stock with a bedslinger. I used double-sided Gorilla Tape to hold this to the inside of my desk wall and it held a 1kg spool without any issue during printing. It was designed to be able to print flat. If the demand is there I can add some countersink holes for actual screws to mount it.
