Pinpad keypad 4x4 matrix keyboard for Arduino, ESP8266 or ESP32
thingiverse
Pinpad base plate and cover plate for those simple 4x4 matrix pinpad keypad keyboards that can be used with microcontrollers like Arduino, ESP8622 or ESP32. No screws required, the cover plate just fits snugly over the base plate. You could use some glue to secure them, but I have not. Infill, resolution, adhesion settings shouldn't matter much so it depends on your personal preference and your printer. I used 30% infill with resolution of 0.15mm and adhesion set to brim. The needed electronics hardware can be purchased for around $3, for example at https://www.aliexpress.com/item/4000641987380.html or https://www.aliexpress.com/wholesale?SearchText=keypad+matrix+arduino
