Sonoff T1 US/AU/NZ Screw-on Mount

thingiverse

I have a problem where the clip on the sonoff light switches is not strong enough to keep the switch tight to the wall (the wires bunched behind the switch tend to push it out). I tried some other designs on thingiverse but, although they helped with some of my switches by providing additional space, others were more stubborn, so I designed this plate and cover system so that I could screw the mount on and ensure that things stayed in place. Not totally sure on the screws, because they came out of an assortment, but I'm pretty sure they're M4x20mm. The idea is that you put nuts in the hexagonal holes (these are designed to tightly fit a nut that measures 6.8mm from flat edge to flat edge, if that helps). This side faces the wall and screws on as per the normal bracket (so the captive nuts are now hidden). The cover then goes on over the switch and screws down.
