This is a simple stand for the Airspy Mini software defined radio. 4.2mm mounting holes are provided to secure the stand to a surface. Note, I have only printed this using SLA printing, and its dimensions are perfect for my Sparkmaker FHD printer, and allow for a slight interference fit of the Airspy Mini into the stand.
Quick update on this design: It was mentioned to me that it would be nice if the holes in the side of the stand were rectangular rather than round, to allow for heatsinks to be added on the sides of the stand. I modified the design to include the 19mm x 14mm rectangular cutouts, to allow for as large of a heatsink as I could.
I actually used the Sparkmaker FDM printer but that wasn't a choice. The Photon is pretty close.
