Missing layers in optics module
I've been looking very carefully at the optics module STLs generated in !307 (merged) and noticed that all of them have the lens gripper floating about 1mm above the bottom of the cut-out for the optics module. I believe this was an error introduced in 446c3c7c where the relevant cut-out was refactored into rms_mount_cutout()
in lib_optics.scad
.
I will add a fix to !307 (merged) to move the floor back to its original level, possibly plus tiny()
to ensure everything joins together in a watertight way.
