Gardyn yCube Nursery Support with No Legs

This is a nursery tray for Gardyn yCubes that is designed to specifically fit this seed starter tray on Amazon.  https://www.amazon.com/gp/product/B086X2Z8P8/   This from-scratch remix is inspired by the design of the RainyDayHiker tray, and retains the same 5 openings and finger cutouts (which also allow the water level to be easily observed), which I liked.  I found the legs on the original design to be a bit wobbly, however, so this variation removes the legs, and sits on the rim of the container with a lip to keep it from moving around.
