Simple IO Plate for a SuperMicro X9SRI-F Motherboard, in case you, like me, buy one used and it doesn't come with one. I believe this will also fit other SuperMicro motherboards, such as the X7SPA-H.
You may want to print the upper projection a bit thinner than I have modeled here, scale or cut in the slicer, or try the included FreeCAD file (use v0.20.1 for best results.)
The author marked this model as their own original creation.
