The easiest thing to do is to shim the camera rather than reprint the optics again. We really need to document this better. I have made an issue on GitLab
I realise we don’t have any shims in the repository So I will start a merge request to add them in.
For now you can try printing these (should be very quick). By stacking them behind the camera you can make the correct height.
