About this 3D model

This is a Keychain version of Emmett's screwless heart gears! I'm still working on getting the scale right (small enough for a keychain, but big enough to print the details) As it is, It needs a rather large fan blowing across the print to keep the gears from getting mangled. Current scaling = .5 All parts are the same except Gear8, which has a hole through the tip for a keyring.
