Mini-Rocket
==========
Sized for a standard (24mm) Estes C11/D engine
Separate nose cone with hook for shock-cord and parachute
Fins chamfered for spin
Fin retainer ring for added stability
Large aft surface area provided by fins and retainer ring pull center of pressure behind center of gravity for stability given high-power engine and short length
According to Makerware, Total Weight (without engine): 72g
According to openrocket approximations:
max height: 287m
takeoff velocity: 17.2m/s
velocity at deployment: 14.9m/s
max velocity: 102m/s
stability: 0.657cal (anyone who knows what that means, let me know - I couldn't find a clear/succinct answer)

Designed not to need supports or rafts, minimizing assembly and printing time/material
Thick walls (designed walls, not print shells) are sturdy for continued reuse (working on thinning a little bit to reduce weight and still print simply)
