small part trays.

thingiverse

I'm designing a set of project organizers to help me stay on top of things. The plan involves using trays along with a modular shelving system to keep them organized. As this is still an early phase, I'd love any input that might be helpful in finalizing the design. One potential improvement I'm considering involves creating three different tray sizes: 5x3.5 inches, 5x5 inches, and 5x8 inches - each one with a uniform height of 0.75 inches.
