Full body protective case for the USB FM transmitter module sold on Amazon. I've included several options for tops and bottoms. One top is specifically designed to be printed with TPU for the effect of being able push the buttons through the case. The specs I used to print it are included in the images. Note: printing both top and bottom out of TPU works but doesn't snap together as well as TPU/PLA or PLA/PLA.
One of the case bottoms has two holes for either a lanyard or screws (tiny ones) to mount the transmitter,
The author marked this model as their own original creation.
