Case for Tang Nano 20K FPGA

I designed this simple case for the Tang Nano 20K FPGA. All features should be accessible, although I don’t have an LCD screen to verify if the connector slot fits perfectly.

The case uses four M3xL4xD4.5 brass inserts, and the included .3mf file contains additional geometry to increase thickness around the inserts to avoid excessive deformation.
 

I created the model in FreeCAD, my first time using it. While I’m aware of a few areas that could be improved, I’m not very motivated to go back through the feature tree right now. Maybe I’ll revisit it with the next major FreeCAD release. I have attached the original design file for anyone willing to give it a try.
 

As it stands, the case fits well and holds firmly. The tolerances turned out quite good. The buttons are a bit stiff but still functional. You might encounter issues if you use the soldered header version, though I believe that’s more of a board design limitation (the LCD connector sits quite close).
 

I hope someone else finds this model useful!
