Test Grid of Cubes

I made this because I had trouble with excessive ooze and poor routing with this LCD mount for the Ord Hadron: http://www.thingiverse.com/thing:91502
This test part was an efficient way to test settings for the widely spaced pillars without using as much material.

I had an issue where a slicer would do perimeters of four posts, then go around again to do infill, which was a lot of wasted motion. I wanted make a quick test for slicers that don't consume much material, so here it is. The wide spread version helps test retraction, to make sure ooze doesn't start building spiderwebs.

Each cube is 7mm on a side, the normal set is spaced 30mm between parts on rows and columns, the wide spread set is spaced 120mm between rows and columns as a more extreme test of retraction settings.
