I have finally gotten around to getting an enclosure designed up for the IR Cool panel that I am happy with, This is going to be offered for sale standalone in a few weeks time, It will be SLS printed so will have a nice smooth white finish you can paint if you so desire.
The unit is 45mm wide by 164mm High and 35mm deep with keyholes on the back and sides for mounting, and holes for the cable to pass through.
The listing for the enclosure to be purchased here is https://tekcreations.space/product/f18-hornet-ir-cool-panel-enclosure/
If you have the IR Cool Panel Controller already and a 3d printer and want to print this yourself it is freely available here
