Dual 18650 Battery Sled

This Dual 18650 Battery Sled is a remix of Vape4D's 18650SSL http://www.thingiverse.com/thing:73960. I added my updated revision of this sled. I have fixed some slicing issues present in the original design and fitted it for Keystone AA connectors. This design is optimized for a series configuration. I will add a parallel version in the future.
