Starship-shaped Hubsan Q4 prop guards

Simple outline prop guards for the Hubsan Q4 micro quadcopter.

I believe this is identical to the Estes Proto X micro quadcopter, but very slightly larger than the Cheerson CX10.

Procedurally generated in OpenSCAD so in theory I could produce versions for other micro-quads if I can get hold of the motor dimensions.

UPDATE June 5, 2015: Added models for Cheerson CX10 as requested
