Single tray detail

One removable tray with material callouts, joinery, and the finger cutout that lets you grab and lift.

Assumed dimensions, easy to tune. Carcass is 16 by 10 by 11 inches with four equal 2.5" tiers. Each tier holds four trays at 3.5"W by 2.3"D by 2.25"H. Trays sit flat on each tread, no angled cleats, which keeps the build simple and gives clean clearance for pen tops above each rim.

Material call. Baltic birch plywood at 1/2" gives the carcass strength and a clean laminated edge. Basswood at 1/4" makes the trays light enough to lift one-handed with pens loaded. Total weight should land near 4 to 5 lb empty.

Joinery. Butt joints with wood glue and a few 23ga pin nails or brad nails. No fasteners visible from the front. The stair structure self-locates inside the carcass once the back panel is on.
