I liked the original concept for housing the nodemcu/konnected hardware but wanted a few changes. I use two seperate relay boards rather than one 2 channel board. Also re-orientated the box mouting position and put a sliding lid on it with some ventalation for the hardware.
I have included my fusion 360 file for modification but I warn you, it is a mess. This was a bit of a brute force job.
