Magnetic Parts Tray

Loose part tray

A tray I made to hold loose screws and parts during tinkering. Easy enough to write down "A - Screws inner controller ribbon" and "B - Screws outer shell" in a notebook or post-it nearby. The table I have it placed on is metal so the magnets hold the gadget a bit firmer in place, as well as holding the screws in place inside.

You have 9 bowls where 8 of them are labeled. If you are working on bigger projects with more loose parts you can use it as 4 big bowls instead. The middle bowl is intended as a "this is the screw i'm using right now"-temporary holding place. There's a slight lip on the rim of the bowls so screws/washers/nuts are easier to pick up.

I printed this with 0.2 but it's a bit rough in the bottom of the 'bowls', so I can suggest trying 0.16 or 0.12 if you want it smoother, but I have not tested it.

To print the model you will need:

• 4 pcs "Threaded_magnet_holder.stl"
• 1 pcs "tray.stl"

I recommend printing a tester first to see if your printer can handle the tolerances:

• 1 pcs "Threaded_magnet_holder.stl"
• 1 pcs "tolerance_tester.stl"

The magnets used are ⌀10mm & 1.8mm thick. These will need a bit of force to push in. If you regret placing them and want them back, just use another magnet to pull it back.
