I printed these to help keep things organized around my printer. There are 2 version. One is just a simple tray, the other has a tool holder at one end for storing extra nozzles and standoffs for my quick change hot end.
I used a .7mm nozzle to cut down printing time, 2 perimeters and 50% infill. You really need to make sure your prints stick to the bed so you have a flat bottom! I printed these in PLA.
