Doorbell Chime Grill

thingiverse

A custom-designed speaker grill for North America's dual-wall plate perfectly accommodates a 3-inch speaker, an SD card reader, and all electronic components fit snugly behind. A protective plate has been expertly crafted, but not attached here as its design can be easily tailored to suit your specific breadboard needs; simply add it with 1mm thickness and precise holes in the correct positions.
