Parametric Stacking Tray Rack
 

It's a flat tray with drainage holes sitting on four little legs, and the legs drop into sockets on the tray below, so you can stack as many as you want. Air gets around everything and water just drips through.
 

The whole thing is parametric, so you set the size, height, leg length, and hole pattern to fit whatever you've got. Pick from honeycomb, square grid, round holes, or slots depending on what you're drying or how much airflow you want. Corners are rounded and there's a solid rim so it doesn't feel flimsy.
 

Print notes: it comes out flat side down with the legs pointing up, so no supports needed and it sticks to the bed fine. Print two or three and stack them. I run it in PETG since it lives near the sink, but PLA is totally fine for dry stuff and organizing parts.
 

Change the numbers in the customizer and make it your size. If you print one I'd love to see it.
