NSphere
thingiverse
The n-Sphere toy is an educational puzzle designed for my son, featuring a sphere that can be assembled using 6 tiles with any rotation and still maintain a continuous topology of ridges and grooves on its outer surface. This flat-based version requires no support during printing with a makerbot. Version 2 has been updated for medium resolution prints, available at http://www.thingiverse.com/thing:88003. A full spherical shell version is also available in baseball, racquetball, and golf ball sizes on Shapeways, priced at approximately $69, $39, and $21 respectively.
