Print in vase mode with .8 nozzle or like the settings in the provided 3mf file with a .4 nozzle, 2 walls, 0 infill and top layers, 4 bottom layers. Because of the rounded corners along the outside edges, there are several bin shapes to fit the tray as best as possible. I've labeled them accordingly. The plano trays labeled RR-LF and LR-RF are for the corners (Right Rear-Left Front & Left Rear-Right Front). The PlanoTray1 is for anything but the 2 corners. And then the lidded versions for extra small items that could slip between the dividers of the plano tray itself. Print the lids normally, I did mine solid.
