Just in time for Valentine's I've updated my Heart Gears. These use my new snap pin library, so they print more reliably and are much easier to assemble. I've also included three different gear ratios so you can choose how much frustration you wish to impart. Assembly instructions can be found in this video: youtu.be/O-qwmRwOpFQ I didn't make this design Customizer-friendly, because there aren't really changeable parameters. However, the OpenSCAD file has been rewritten and greatly simplified to make it easier to cut gears out of your own shape. I'm always excited to see new derivative gear mashups.
