Simple modular PCIe card stand. Assembled with the included dowels and biscuits. I was able to print cleanly without support. Printed on Bambu Lab X1 with Bambu Lab PLA Basic.

.3mf file configured with two plates, two 1-unit PCIe card holders and two 2-unit PCIe card holders.

Print with an ESD safe filament if you're concerned about that stuff.
