Smart switch replacement cover (Sonoff)

Replacement cover for a smart wifi touch light switch. My particular model is Sonoff T1 EU 2C, but there might be other rebrands and compatible versions.

To make it a bit more fun I added versions with cat ears for 2 channels and alien ears for 3 channels.

**Note this for a mains electrical device, which can be a fire hazard.** While not directly in contact with live wires, the cover could be subjected to high heat if the device malfunctions. I advise against printing in PLA or other filaments that can combust when exposed to heat. ABS should be fine, or even better PETG because it does not sustain a flame.
