Geared Heart, Hand Crank Edition

myminifactory

Human-eared hearts captivate my imagination (maybe because I was born on Valentine's Day?). I'm still trying to figure out who came up with the first one. Unfortunately, I couldn't track down the originator of geared hearts as I didn't know they'd been around for a while. For instance, I discovered this 2008 video of a paper hand-cranked geared heart at http://www.youtube.com/watch?v=70dKZjP4NOo and was thoroughly intrigued. Inspired by the paper hand-cranked geared heart video and Emmett's ingenious geared heart design, yet having too little time to create one entirely on my own, I incorporated Emmett's geared heart into this design to build my hand-cranked PLA version of the hand-cranked paper geared heart. The video of my version is at http://www.youtube.com/watch?v=6V-IYuWghAQ. And if you don't want to crank the heart by hand, a motorized version is available. This design was created using SketchUp 8 and printed in PLA on a Replicator 2 with MakerWare 2.3.3.42 "Standard" settings. UPDATES: 1) I added "Heart Base 1-2.stl" to work with Emmett's "HeartGears1-2.stl." It hasn't been tested yet, so printer beware!
