i got the kits from Bitcoin Veterans p2p: 2 devices with 3D-printed cases, very basic design. briefly looking online, i am struggling to find a vendor who accepts bitcoin, but perhaps Bitcoin Veterans can ship a package of those - great for kids to play with. reportedly these range up to 25mi line-of-sight radius and 254km record. if by chance u still use facebook, check a link below 😅.

some people do not use a case, it still sits in a plastic baggie. i bet cryptocloaks could make a cypherpunky design. the assembly is 3 pieces put together in the correct order (something about chip frying if the antenna is not put on 1st)
