Fed/2/2018 Update:
I uploaded a new version of the box with better opening positions "Sonoff 1 v2:

And uploaded a blank box with only one hole for the wires to go in and out from, So first install the wires and then set the board in place neet.

And uploaded a cover with a small logo in order to reach the buttons without opening the cover.

Please upload your prints and recommendations for better parts.
