After much trial and error, I’ve finally perfected my light switch enough to share it. This will allow you to fit a sonoff inside a normal North America style receptacle outlet box, and fit in nicely behind a Decora style switch plate.

This uses a Sonoff basic flashed with the Tasmota firmware, which full integrates into home assistant over MQTT.

For the Sonoff enclosure you will need to download Mmasson’s project here and use just the enclosure files: https://www.thingiverse.com/thing:2804973

Then comes my decora switch attachment here: https://www.thingiverse.com/thing:2830060

If anyone is interested in a capacitive touch style switch, I’ve also designed this style: https://www.thingiverse.com/thing:2820884

Very nice! I do have some Sonoff devices and 2 3D printers. You print these in PLA or ABS?

These are printed using PLA. I like working with PLA much more than ABS. When it comes down to sanding and finishing a product, I find PLA just works better and has less problems (little to no shrinkage).

PLA is definitely easier to work with but I think ABS is much easier to sand (especially as PLA gets that “haze” over it once you sand it).

I find when you work your way up to 2000 grit paper, the haze is very little with PLA. Once you’re all smooth, any car polish on a foam pad will buff the haze to a shiny sheen finish. I haven’t worked too much with ABS for various reasons, PLA has always been my personal choice. Smells better in my house lol.

Definitely smells better! The wood PLA filament smells amazing :slight_smile:

Does it ever! My partner thought I was chopping up wood in the basement haha. I love it. My most recent print ended up clogging the nozzle though, so I’m going to wait to print more wood until I get some more nozzles as a backup.
