I purchased the HackRF Pro by Great Scott Gadgets recently, and as it seems to follow me around a bit I thought I should add a bit of protection for if/when I drop it, and maybe add a touch of colour. I have printed mine in TPU95A, so this or softer should be fine.

Special care should be taken in fitting this to not put excessive force on connectors/buttons/etc, and it is a tight fit. So if you are not sure, stop what you are doing and take it off.

The case should be fitted by inserting the USB-C/P1/P2 end in first, then carefully lifting the center of the opposite end over the RF connector and wiggling gently into place.
