Quadcopter Motor mount

This acts as both the motor mount and landing strut for the quadcopter my friend and I are building. This may be over the z-axis limit on some makerbots, especially if you have an ABP. The mount will accept 3/8" dia carbon fiber rod, and the smaller hole will allow you to feed the wires through for the motor and any other lights or accessories. This was designed to be easily printed on a makerbot. I'm open to suggestions or ideas on improvement. The current model is Ver4.
