What I would do with on of these! User chall2009 from thingiverse created this rocket launcher using his Makerbot Replicator 2 3D Printer, Arduino boards and some other supplies . The Rocket itself and the case for the launch control are both 3D printed.

The Arduino code for the rocket launcher is available here: https://github.com/chall2009/Arduino...master/LICENSE
