Customizable openscad webcam cover

Suitable for larger webcams / videoconference cameras
The cover is a flap that lifts back up and over 270 degrees out of the way.
All dimensions can be altered to suit your webcam.
OPENSCAD code is commented, so hopefully useful to all.
I made the "window frame" wide as my camera had extra auto focus sensors which I didn't want to obscure when the flap was open and camera in use.
