What do you do if you need to rotate a star tracker by 90° but the device does not have mounting points there; you add those in CAD and the next iteration will have it but for a quick solution sometimes it is good to have a mechanical workshop, a CNC mill and other equipment to make such modifications.
P.S. the reason this picture is through the window is not (only) due the nice looks but also because I was on the way to my lunch break when I saw my colleagues making interesting things in the workshop.
