Yet another poop bucket, I needed one that would work with the magnets I had. Doesn't interfere with spools on the back.

Simple 100mm x 100mm square. Fits 2 12x5mm magnets. Sticks to the printer securely and will hold when moving printer around

1.5mm thick walls for easy printing and good strength. NO SUPPORTS necessary. Prints good at 0.28mm Layer height
