Slanted 18650 Sled

I updated the "Slanted Sled" model (http://www.thingiverse.com/thing:723431) , gave it an additional 0.8mm of length in the sled for slightly larger than normal 18650 batteries. For those with fitment issues previously make sure you are using the Keystone 209 and 228 battery contacts (see photos).

I've updated the STL to include the missing face from the last upload(6Jun15-2239EST)
