Stackable Storage Tray

I started this based on a need to clean up the stack of junk gathering next to my resin printer. The design will hold a standard sized box of nitrile gloves, 2 resin trays, or anything you can think to stuff in there within the size limitations. These SLT files include the main tray, the top tray, and 2 different size extensions to expand the height by either 20mm, 40mm, or some combination of those 2 sizes.

This is my first design from scratch, I hope someone else finds it as useful as I do.
