This instructable has been in the works for quite a while and should have been finished when I did version 1. But I'm so lazy so it didn't come out when it should have, yada, yada, yada. Also if you want to make this for a bigger battery you should adjust the dimensions accordingly.
Any way, enjoy!

An Exacto Knife or scissors
A pen
A ruler
You also need:
Aluminum foil about 8cm long and 2cm wide or 4 inches long and 1 inch wide
Cardboard from a cereal box about 6.5cm long and 3cm wide or 2.6 inches long by 1.2 inches wide
Electrical tape
I reccomend you use the metric measurements because they are a little more exact and they are the only measurments I will use from here on out. Also don't cut out your materials just yet as you may need a slightly larger piece.
