Make the chassis a little larger to make the sizes easier to calculate with.
Make the laser a bit bigger (it really is!) and lower it along with the mirror and the hole in the wall.
In reality we have to transport the mirror along some kind of mount.
Add forward/backward transport. Move things out of the way as necessary.
Make the mirror transport mount twice as high so we can attach things to it.
