About this 3D model

Solar powered valentine for my wife. Video of prototype at http://www.youtube.com/watch?v=cMVpbErYY2E. The file "Heart.stl" contains a "You !" heart half as opposed to a "Lora" heart half. Using the electronics from the inside of a dollar store animated solar powered "devil" (purchased at a local dollar store, for a dollar no less, but also available online), 8 12mm by 3mm neodymium magnets (purchased at a local hardware store but also available online) and a 65mm by 1.6mm "yarn darner" sewing needle (purchased at a local sewing center but also available on line as "Dritz 56YD"), this Valentine will spin as long as adequate light shines on the solar cell. Designed using Sketchup 8 (free version), and printed on a Makerbot Replicator 2 in PLA using Makerware 2.3.3.42 "Standard" settings.
