HC-06 Bluetooth Module Housing

I got a HC-06 bluetooth module for wirelessly connecting to my PixHawk flight controller. As it is dangerous to use an unprotected board within my copter I designed a litte housing for it.
The opening for the connector pins is asymmetric with more space in one direcrtion. This is intended for keying the connector .
Finally I used two BEC 2 pin connectors which are glued together using CA to get a 4 pin connector. They are asymetric, so they will utilise the keying and fully plug-in only in one
