3DChameleon Mk4 Pro mount for a metal rack

I designed a mount for 3DChameleon Mk4 Pro. The cables come out from the side of the case. You can attach the case and 3DChameleon unit to a metal rack with the hooks.

Note: the hook design is based on the frame of the metal rack in my house (Width 24 mm, Thickness 5 mm).
