2x2 Square Polypanel with PCB standoffs

I used the Solidworks Polypanel snap connector design from here. More info on polypanels can be found here.This 2x2 Polypanel is part of a test fixture for an LED display. I added standoffs to hold an LED array. It can easily be modified to accommodate PCBAs up to 2.8" square.Printed at 0.2mm layer height, 3 perimeters, 15% infill and no supports.
