About this 3D model

This is a modification of neoarchaics "NSphere" http://www.thingiverse.com/thing:81449 It consists of twelve pieces that have these carvings on their surface and can be connected to each other to form a sphere of the size of a tennis-ball. No matter how the sphere is assembeled the carvings on its surface will always line up and make a pattern of lines. If you turn one piece or switch positions with another the pattern on the sphere will change but no matter what you do it will always make sense. This makes it a "antipuzzle": There are no wrong solutions, just different ones.... Make your own collection of modules, slice, print and assemble them and have fun... ;-) P.S: Post a picture when you made one.
