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
