PicoPix max (beamer) tilted ceiling support

I designed my own support for the Phillips Pico Pix max beamer.
Instead of using a 1/4" screw I decided to design a slot-in piece that works fine with the support included in the ppm package, so that I did not need extra parts.
I think it's even better than a screw support, you can attach and detach the ppm really quickly from the ceiling: you just slide it in and when it's in place it falls down by 3mm and it sits there, no way to fall off.
My ceiling is 30° inclination so this design matches my specific needs.
Happy printing!
