Text Sphere
thingiverse
This is a generalized version of the PI Sphere. You can calculate relative parameters, but I've left more parameters open for you to customize your favorite style. Simply input your own text, bottom symbol, style, top radius, bottom radius and thickness to get started. If you want to change the sphere's radius or font name, try adjusting the font size, char gap, floor density and top offset to make it look pretty. You can even find interesting things about PI. For more information, check out the OpenSCAD Documentation in English.
