The 3-cell power supply

This is a 3 coin cell assembly for a Wii Light pen I have assembled for a friend of mine. Each coin cell is providing 1.5 volts and with three of them, you get 4.5volts, close enough to match the original 5volt USB voltage. What I am showing is how you would need to create some kind of battery holder for them.

Most probably, create a tube inside the extractor
and then stuff the batteries in. But you also have
to make sure you can get them out when you need
to change batteries since they're so small, they can
get exhausted very fast, methinks
