Project Case - 4xAAA with switch

thingiverse

I was testing various headphone amplifier boards purchased online and needed power/mounting solutions. This case is actually version two, designed to accommodate different boards without any specific fitment - I simply hot glue them to the bottom. The holes on either end are intended for in/out cord management (a cost-effective alternative to panel mount jacks). This case can hold four AAA batteries and a power switch, with ample space for a circuit board installation. To make this work, you will need AAA terminals. Additionally, I used threaded brass inserts (M2) for the doors with a socket cap screw, although it's not essential.
