Maker tray is a 3d printable parts tray that lets you organize your small parts/components during assembly/disassembly/storage. Yes storage! you can laser cut or 3d print a lid with matching magnets to store your parts without the risk of them ending up all over your work bench or floor.
There are 2 versions of this tray: with magnets and without magnets. Both versions have 6x3mm magnets on top to hold a lid but only one version uses 32x1.6mm magnets on the bottom for holding onto magnet things like screws.
