Type C Battery Charging Cradle
thingiverse
One of my devices consumes C-Type batteries. I bought accums of C size, but I did not want to buy a charger as I had a good AA bateries charger. So I made a cradle for C-size batteries and an AA-size adapter. Push batteries to the cradle, adapters to the charger and you can charge C-type batteries Print Settings Printer Brand: RepRap Printer: Graber i3 Rafts: No Supports: No Resolution: 0.2mm layer Infill: 30% Post-Printing Glue 'spring' parts to the cradle at the minus side. These springs should help keeping a good contact between contact pads and battery As a connector pads I used small pieces of a metal can. First solder wires to metal pads, then glue pads to the plastic. See soldering scheme on the photo.
