NSphere Mini (tile type:4)

n-Sphere Mini Tile no. 4 (of 6 options) Redesigned with a thinner shell for reduced cost at a racquetball sized scale. Designed as an educational toy for my son, the n-Sphere toy is a little puzzle box with no wrong answers. The sphere can be assembled any combination of 6 tiles oriented in any rotation and will always yield a continuous topology of ridges and grooves along the outer surface.
