Camel 3D Block Zoo
pinshape
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. You can watch a video of my designing this toy at https://youtu.be/HgQeDQ8pe0M. I would suggest printing with supports, 10% infill, 0.2 mm layer height.
