Sonoff Basic R2 wall box - Decora

I really liked what Old-Steve had done here with the SonOff basic wall j-box mount. It is fantastic in every way. Great engineering, makes use of existing SonOff screws, clean design and so on.

But SonOff changes the design of the Basic over time. When I bought, all of mine were the Basic R2 V1.3. I noticed that there is a small problem with the housing. Steve's original design is expecting a 1.8mm thick PCB. But the new Basic R2 has a 1.1mm PCB. Only .7mm, but this small amount of slop is enough that when the board is seated in the housing, the pushbutton may be just far enough back that doesn't make contact with the spring button mechanism in the housing. You could put some foam or something to compress the board against the housing cover. But instead I decided to add small .7 mm fillers underneath the existing ones to accommodate the thinner PCBs. Also be aware that for the Housing, you need might need to scale it in your slicer to get it to the exact dimensions. The
