Arduino Buzzer (Push Button, Dash-Button) Box
thingiverse
This is a small case for an Arduino nano and a push button with a cut for the USB port. I used this button with an led ring. I switched the led with a small boost converter for the 12V led power. (the internal resistor of the led was fixed inside the button). Button: https://www.amazon.de/dp/B06XKVW3ZZ/ref=pe_3044161_189395811_TE_dp_1 The other nice idea, is to use an esp32 or esp8266 and build a small mqtt enabled button. If you print the case with transparent filament you can place some leds in it.
