Drawing models after Harding

Long overdue, but this is what I made as a teaching aid (and for my own practice). They are shapes based off a book by a 19th century artist and art teacher, James Duffield Harding. Link

I made them using Sketchup and a plugin for paper models. They measure about 6 x 6 x 6 cm, so that it is possible to make the models from sheets of A4 paper.

As you can see from the first image, they are also meant to be used in various combinations, to form simple architectural forms. I am thinking of a way to mass produce these, so that we can have more forms to play with.
