Enclosure/Mount for Keenovo Heater Control Box

I have a Creality CR-10-S5 and a Keenovo heater for my print bed.
To keep the wires clear, it is better to mount the control box high.
So I made this holder for the control box, which allows you to mount it with standard screws and t-nuts to the top of the Creality frame.
Back insert is friction fit.
