After I've made the Gear Corner Turning Octahedron
, I thougt that the same face pattern could apply for a tetrahedron too (to make a Gear Pyraminx with different gears ratio and face center element) and designed a Gear Halpern-Meier Tetrahedron. The whole designing process of this puzzle was captured by SolidWorks "Capture video" function. It does not track mouse movements or surfing the menus - it only captures the changes in the project window. So the activity that really takes 1 hour is saved as a 2-4 minute video.
You're welcome to see how a new puzzle is designed from an empty drawing board to the finished hollowed parts ready for 3D-printing at Shapeways. Here are the YouTube links to 4 video parts (total duration is ~17 min):Part 1Part 2Part 3Part 4
I would love to see how other designers create puzzles with other CAD software, would someone share similar video?
