Customizable gyro toy wrapped with engraved text

thingiverse

I made this using Jamie_K's [geodesic sphere for OpenSCAD](https://www.thingiverse.com/thing:1484333) because I always felt that the default sphere geometry in OpenSCAD wasn't suited for this. So here is a customizable gyro toy (as if Thingiverse hasn't enough of them already). The customizations include: - Dimensions (outer diameter, center disc diameter, height or thickness) - Number of rings - Optional engraved text to wrap around outer ring - Decoration on the center disc (recycle symbol, smiley face, or blank) The included STL uses the .scad file default parameters (a smiley decoration with no monogram). If you want further customization, you must edit the OpenSCAD file yourself (you can use the OpenSCAD customizer for this). Be patient waiting for OpenSCAD to render; it takes a long time. It also takes a long time to save the STL file; wait for "STL export finished" message to appear in the console window. The photograph shows an example of customizing with a monogram and recycle symbol, with multiple layer colors. The geometry is simple enough: the rings are concentric cross-sections of spherical shells, with pivot bearings across a diameter, and each pivot axis is orthogonal to the pivot axis of the next ring.
