Magazine Battery holder (AAA)

thingiverse

This is a rework of the spring for the AAA magazine. It is a resized copy of the AA version which is much more flexible that the AAA version. I also found a way to make it more durable when flexing. I put this in a sealed container with some acetone overnight. The spring is still stiff but it flexes, almost rubber-like. Do not let the acetone touch the spring though. Just uses the fumes to rubberize it.
