This is a stackable & locking pressure pot tray system that I designed. It is meant to go in a 9in wide by 9in deep pressure pot. It is 3in high. 3 trays will fit in one pot.

If you want to resize it, I recommend you just expand the circle and move the handle slots outward.

I used 5.2mm or 1/4in plywood

This is meant for personal use only. You can use the tray for commercial use, but do not sell the plans nor the product. You can charge for cutting of course.
