Very simple and easy to print magnetic screw tray with 9 integrated magnets. Magnets are snuggly press-fitted, so glue is not necessary. There is also an optional 1 layer thick sheet, that can be used as a cover for the magnets. It also can be left as is, or fixed with a few drops of glue.

Tray dimensions: 10cm x 8cm

Magnets: 4mm x 1.5mm (9 pieces)
