This is the collection of fire hydrant models featured on the cover of my book "Blender Scripting with Python" in a ready to slice & print STL file. Learn more about how they are procedurally generated from scratch using Blender Python in Chapter 5 http://leanpub.com/blenderscriptingwithpython
The models are identical to the ones from the book except for scaled 3X to produce prints about 2 to 3 cm tall. The sample set in the photos is printed with silk copper PLA with skirt adhesion and no support. Enjoy!
