About this 3D model

This is a motor drive for the GE "Build Your Own Jet Engine". It replaces the hand crank of the original. I designed this to use a motor, switch and battery holder available from any RadioShack store. The gearbox is a 243:1 speed reduction based on the design from "mirk", but shrunk to 50%. The drive chain and drive gears are based on the design by "peanut", only shrunk in width. I also had to re-draw both of these as Slic3r was messing up on the edited versions I originally tried. ##Build Instruction Videos: http://youtu.be/eEZHopwp_uw http://youtu.be/0vsQaENOMUE http://youtu.be/94io_2Rzg4M http://youtu.be/1e-gh9qcMAo http://youtu.be/t0UVHZkPXHU http://youtu.be/Mr3x3RQa9MQ http://youtu.be/Dw0kpxK5sPE http://youtu.be/cVXT8cPgXAs
