A 3x3 parts tray for small parts that uses the gridfinity system to allow for trays to be stacked on top of each other. The dishes have serrations and a smooth fillet that means parts like washers and small screws dont get stuck to the bottom of the disk and can easily pulled up and out of the dish.

I have also provided STEP/SLDPRT files to allow you to go in and modify the dish further.

Print settings are fairly unimportant due to high tolerances but a lower layer height allows for easier removal of parts from the trays due to less stair stepping.
