This is an IO shield for the Infamous Dell Optiplex 3050 MT motherboard for if you do a case swap. As this is an OEM PC the IO shield is built into the case and not really easily removable. I tried to just modify other peoples designs to work for this mobo but I couldn't get the models to load entirely into Tinkercad so I just measured it out and drew it up from scratch. Feel free to remix this or whatever.

Easy peasy, just basic settings, 100 percent infill and let her buck for 45 minutes or so and come back to an IO shield.

Just measured with a digital caliper and designed in Tinkercad.
