A simple sorting/organizing tray for small parts, such as hardware, jewelry, or Lego bricks. 

I tried to be as material efficient as possible when creating this. All walls are 0.8 mm, or 2 wall loops thick. Rounded corners help with getting tiny parts out of the tray's compartments. 

I designed two variations for the trays with different-sized compartments. The trays are stackable and can be stacked in any order or orientation. The boxes have small registration bumps on the corners to keep them aligned. There is an optional lid as well that marries with the registration bumps. It does not latch, but the bumps keep it in place. The lid has a thumb groove on one edge to help remove it. 

The overall size of one tray is 200 x 200 x 31 mm. This should fit most printers; I designed it to fit my older Anycubic which has a build plate of 210 x 210. 

 

UPDATE 5-Jan-25

I've added a new tray that is 200 x 200 x 20 with only small compartments.
