Manta Ray 3D Block Zoo

Summary I was inspired by the 3D Printing Professor's first 3D Block Zoo entry: http://www.thingiverse.com/thing:1927926 Of course, I wanted to do them in FreeCAD instead of Tinkercad. I would suggest printing with supports, 10% infill, 0.2 mm layer height. I am using the new version of NetFabb to check my designs. I'm not sure that they all needed to be repaired, but I checked the automatic repair option for loading the files. Thus, they all have the (repaired) after them, just in case.
