My 12 year old CMoy headphone amplifier build got a battery compartment upgrade! The battery has banged around in there for 13 years, but now it will stay there nice and firm. Fun little design, easy print. I got the radius slightly wrong on the corners but it fits well anyway. #Electronics #3DPrinting

I should mention that it used a 9V battery for a long time, but in the last few years I have run it with a 3.7V rechargeable RC car battery and a USB battery charger/boost converter board. That all fits in the 9V's spot. I just pop the lid and attach the USB cable to charge.
