Quadcopter (Drone) Upgrades V2

After finishing building my quadcopter with ordered parts, I noted that the battery would need a case not only to protect it but to hold it without having to use battery velcro straps. Also by locating the battery at the bottom instead of the top of the quadcopter, it provides a better balance and center of gravity.

I designed this parts using openScad,
