thingiverse

If you have a Fitbit and lost your usb charger... now you can print this case and recharge youe device. After printing the case, look at the side with 2 holes. The one in the right is for + and the one in the left is for -. Cut from a sheet of copper or a conductive metal, 2 rectangles of 2x4mm with a thickness < 1mm. Solder the wire at one end of the rectangle and when you place them inside the case point the other end towards the top of the case for better contact. Good luck!
