This is an updated remix of the Single Use Model Rocket (see http://www.thingiverse.com/thing:87495 ). This version has a longer, solid nose to shift the center of gravity forward, and slightly longer fins, to pull the center of pressure backwards.

Prints as a single intact object.

Printed with
Infill 100% (important! to maximize weight in nose)
Speed: 40mm/s
Shells: 3
Layer Height: 0.27

Print time = 1:49
Weight (empty) = 23g
Weight (w/ engine) = 48g

With the center of gravity (CG) moved forward, this version should have better aerodynamics than version 1.

This is designed to house an Estes 'C' standard sized model rocket engine.
See ( http://www.thingiverse.com/thing:88520 ) to adapt to an 'A' sized mini engine.
