C910 webcam mini-mounts

Inspired by TheNewHobbyist's thing, I wanted to make one for my model of lamp-arm, and then for other things :)

So these small parts will allow you to mount directly your C910 logitech webcam to :

*a lamp-arm like the one in the picture
*a 6mm bolt like the one in my small tripod
*or inside a 6mm channel of an aluminium profile
