Hi, I'm hoping to build the BQ Ciclop scanner and have a logitech C920 camera that I could use instead of the C270. I realise that the stl file holding the camera will need to be modified. But I have a few other questions;
1) Why is it necessary to remove the lense cover of the camera? Does the lense cover have a distorting effect on the lasers or is the cover only removed on the C270 so that the camera manual focus may be adjusted?
2) Is the lense center height in the plastic housing a critical dimension?

Thanks in advance.
