Light Shield for Hydroponic Container

I created a light shield for my hydroponic plant containers. I have been saving/reusing the square Good & Gather nut/trail mix containers for Kratky hydroponics for a few years and had tried a few different options for blocking light including tape, adhesive-backed sheeting for shelves, spray paint, and putting them in storage bin covered with reflectix. This shield is a much cleaner look, gives me a bit more flexibility with how plants are arranged in my limited space, and should make cleaning containers much easier. Note: These are printed in vase mode. The hole in the bottom matches the hole in the top of the container. The inner lip on two of the corners was a bit rough where the inner wall met the infill on mine, so you might need to clean up the underside with deburring tool.
