About this 3D model

An animated helicopter pull, push, downhill toy. The main and tail rotors spin as this toy is pushed, pulled or sent down a hill. I printed the prototype gear trains in various colors and designed an open cockpit in order to highlight the operation of gears both beveled and linear to up and coming engineers. Video of the prototype is here: https://www.youtube.com/watch?v=0c_GuncghxQ. My wonderful wife, sister in law, kids, grandkids, nieces and nephews had fun producing the video and audio. Hope you and yours like it as did I. I'm printing more of these things for them, schools, and labs. Designed using Sketchup Make 2015, and printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42 "Standard" Settings (.2mm layer height, 2 shells, 10% infill).
