This single-plate heart gears design is a clever remix that brings all the interlocking magic of the classic heart gears mechanism into one printable file. Perfect for enthusiasts browsing Thingiverse-style 3D print files, this version consolidates every gear onto a square base so you can print the entire toy puzzle in a single run.

The real charm? Watch as heart-shaped gears mesh and spin in sync, creating a hypnotic kinetic effect that's equal parts brain teaser and desk ornament. The OpenSCAD-based design scales beautifully, so whether you're testing the limits of a compact printer or going full-size, the mechanism works smoothly.

Because all the parts print together on one plate, assembly is straightforward—just pop the gears free and start experimenting. It's a satisfying hands-on project that bridges engineering curiosity with a little romance.
