Broken Heart

Create a kinetic sculpture featuring parametric bevel gears, inspired by a similar design at http://www.brainblog.to/item/2008/11/herz-aus-zahnraedern. The entire structure was modeled in OpenSCAD using the Parametric Involute Bevel and Spur Gear script. The gears not only spin but also rotate around their axes, as seen in a YouTube video (http://www.youtube.com/watch?v=Zx28cHA4_KI). However, a better technique for attaching the gears to the central mount is needed before printing. OpenSCAD files are available for all parts, but generating STL files from them may be time-consuming due to numerous components. Collaboration on improving gear attachment methods is welcomed. The assembly requires 3/16 threaded rod, nuts, washers, M4x40 cap screws, half nuts, and a 10mm aluminum tube. Attach five nuts between heart_centre_middle and heart_center_top parts, followed by screwing both onto the threaded rod. Add 10 and 15 tooth inner gears to center pieces using M4 cap screws and nuts. Glue gear outer parts in place after attaching aluminum tube with slots at top and bottom for gripping gears. Slide walls over the tube, install drive gears, crossmount, shaft, and last gear. Finally, attach handle and knob to complete the sculpture. A modification to securely fasten gears in the center is recommended.
