It's a very nice feeling when people starts to create accessories for your inventions. OK, maybe "invention" is too strong word here, but still.

EduardoChamorro designed a 3D printed case for my HC-12 433MHz to HC-06 Bluetooth bridge that I published here last year.

LRS to Bluetooth 3D Printed case

It's small, it has a switch and status LED. It also has integrated LiPo battery and a charger. Awesome!
