Double Smart Button

I recently found myself needing some nice chunky "smart buttons" for a project. I loved the original "emergency button" and wanted to make a double set, so I took the model and hacked it up in TinkerCad to make this pair of buttons.

Prints without supports if you orientate it correctly.

There are two middle sections - one with a hole for your USB cable and one without if you want to use it with a battery.

I highly recommend using the “text” button in Prusa Slicer and a colour change to add your own labels to the buttons.

As with the original you just need to add a couple of tactile buttons, add a few strands of wire and a small microcontroller (ESP8266, ESP32 or RP2040) then you can hook it up with HomeAssistant via ESPHome and use it to trigger all your smart home gadgets and automations.
