Hello!
I designed and printed a nicely ventilated case and cover for my Raspberry Pi 3A+ and RTL-SDR. Attached are the Fusion 360 .f3d files and .stl files.
The design does not accommodate the RasPi 3B/4B board size, though with the .f3d files, anybody can do so.
I hope some folks find it useful, and welcome feedback!
Love this community!
