coin cell battery holder
thingiverse
This design cradles a single 3V coin cell battery. After printing, simply thread wires through the holes - one for voltage and one for ground. The wires within will secure the battery in place. Two small openings allow for optional switch integration (the switch comes with two distinct detents). As shown in the photo, this coin cell holder is paired with a neopixel LED and an attiny85 microcontroller. This combination was used for the 2016 e-textile swatch exchange.
