Type C Battery Charging Cradle

thingiverse

One of my devices runs on C-Type batteries. I purchased accums of C size, but I didn't want to buy a charger since I had a good AA battery charger already. So, I created a cradle for C-size batteries and an AA-size adapter. By pushing batteries into the cradle and adapters into the charger, 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 negative side. These springs should help maintain a good contact between the contact pads and battery. As connector pads, I used small pieces of metal cans. First, solder wires to metal pads, then glue pads to the plastic. Refer to the soldering scheme on the photo for details.
