CubeShere thingy

This is a fun part, inspired by an example image on the K3dsurf page:

However, I designed mine in solidworks since I don't like mesh stuff.

Its pretty basic but its great for testing retract/stringing and jump/lift, and also for illustrating why a minumum layer time setting is critical for a slicer (something NetFabb currently lacks, though I hear the newest beta has it half implemented).
