NOTE: Received word on the forums that the power supply plug and jumper header are different for different versions of the board. This set of files are built to work with the 1.4 rev of the board. Once I get some more details I will update the STL files to accomodate all versions. Thanks!
This is a printable case for your LimeSDR from MyraidRF ( https://www.crowdsupply.com/lime-micro/limesdr ) The case contains four SMA antenna ports and holes for USB and external power interfaces. The LED indicator lights are covered but show through the plastic. Vent holes provided to help keep the FPGA cool. The TX/RX and channel number indicators are indented but not cut through: this allows the user to drip a little paint in there and color the text if desired. The layer is thin (0.4mm) and can be cut away if desired.
This should be pretty easy to print. Use support for lid.
Cleanup and Assembly
Carefully remove excess plastic from the vents (somewhat fragile) and SMA ports (somewhat less fragile). The SMA ports don't need to be perfectly clean, just enough to fit the connector through. Before screwing the PCB into the case I would run the M3 screws through without the PCB to ensure proper alignment. Then, insert screws into base and through board (carefully) and visually inspect. SMA wires can tangle: I wrapped them into a loose loop and used electrical tape to secure.
I used Fusion 360. I was fortunate to get a pre-release board to review and was able to design and fit the case to the actual product.
