Parametric camera mount on 2020 extrusion

Remix of https://www.thingiverse.com/thing:3317579
I made the camera mount parametric to fit other camera modules with square or nearly-square pcb and four screw holes at the corners
I am using m2.5*10 screws to attach the pcb, you can customize the size according to screws you have(diameter under 3mm should be ok)
The model is separated by default to avoid adding support structures, you need to glue two parts together.
You can also customize the hole for cable outlet.
