Microstructures: Pattern0050 0.5mm cell

This is one of the patterns we found from our topological sweep algorithm. It does not have a name, so we call it using its index: pattern0050. It is quite soft. It is a 6x6x6 tiling with 5mm cells.

**Clarification:** This pattern is known to be anisotropic, and it is **not** one of the final selected 6 elastic textures we proposed on "[Elastic Textures](http://vcg.isti.cnr.it/Publications/2015/PZMPCZ15/)" paper published in Siggraph 2015. It is purely designed to test the printers' capability of printing microstructures.
