IR stable camera mount

I had some stability issues with the design by alf249 and therefore I decided to create my own camera housing, which can be fixed in the corner of a Ikea-Lack enclosure.
The new mount has an angle of 45 degree and therefore points exactly in the middle of the enclosure. It can be tilted up and down and fixed by the pattern on the joint.

The additional Parts that are used are:
1xM4 Screw
1xM4 Nut
4x self-tapping screw with 3mm diameter
