Simple bowl parts tray with a magnetic bottom to hold screws and other metal parts.

Print settings 0.2 first layer, 0.16 regular layer height. Pause print after the 25th layer and insert magnets. Uses 24x 1/2 inch square magnets 1/8 inch thick, because I got thousands of them for free. They look like this: https://a.co/d/e4qG4Gg

I'm sure most people don't have these magnets handy but I thought I'd upload just in case. Any other magnets can be substituted as long as they are less than 3.2mm thick
