2xAA in-line battery holder

cults3d

I've got a 2xAA in-line battery holder that's fresh out of the printer. I attempted to replicate existing designs on the market, but those retention tabs always seemed to snap when touched. Okay... I'm working with PLA and don't feel like purchasing alternative materials just for this project. After numerous test prints, I made some adjustments to keep the batteries secure. I added a "clamp" mechanism that allows easy battery replacement. The contact components are built using: 1. An M3x8 round head screw, along with a washer, closed Faston terminal, and standard nut for the positive connection. 2. An M3x16 conical head screw, paired with a pen spring cut in half, a washer, closed Faston terminal, and self-locking nut for the negative connection. I hope this design proves useful to you.
