This is my take on a case for the BladeRF SDR with the XB-300 amplifier.
It gives access to all the ports of the BladeRF and the default ports of the XB-300.
I recommend using PETG with 0.2 layer for the details of the RX/TX graphics with supports for the snap hooks only. I've attached a slices file with all of my recommended options.
