I highly recommend anyone who is not limited to a 6" print bed to make the long version of this case. http://www.thingiverse.com/thing:1016829 It works much better with SMA antennas as the MCX-SMA pigtails are attached to the case.Three part case for the Open source Stratux ADS-B receiver for people with small 3d printers.Supports dual RTL-SDR receivers. Remove the cases and use a small amount of hot glue to secure them to the middle layer. (Nov 6 increase thickness of this part to make space for GPS/AHRS pins)Third layer holds the GPS/AHRS. (Sept 15 Increased thickness of this part to fit the GPS) Added a version of the top case with recessed holes for the M3 bolts that hold it together.Remove cases from RTL-SDR they fit tightly in and I use a tiny bead of hot glue to keep them from popping out. You will need a pair of short (6") USB extension cables.
