Frog 3D Block Zoo

I was inspired by the 3D Printing Professor's first 3D Block Zoo entry:

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.
