3d model description

A quadrisection of a sphere into four identical parts with some novel attributes:

The parts have no overhangs.
The flat \'bottom\' is comp...letely concealed after assembly; there are no flat spots on the exterior of the sphere.
Exterior is made entirely of \'sidewalls\' where the resolution of FDM really shines.

My test samples were built in transparent PVC on a Solido SD300 Pro, but my goal was to design a Makerbot-friendly shape. Based on feedback from friends, I\'ve adjusted the contours so the pieces \'grab\' onto each other after assembly.

3d model print parameters

After you build four of these they should fit together to form a ball. Note: the parts fit together with their build planes at right angles, so it\'ll... doubtless be affected by any geometric distortions.
