379: Dodecahedron

Posted by wonko on March 2, 2012 in geometry |

In search of a new modular to adorn my computer lab, I stubbled across a dodecahedron that looked interesting enough:

Thirty modules later, I began to attempt to construct – after 7 different attempts and modifications I could not find a way to make the modules lock together convincingly.

Defeated, I resorted to a few well-placed pieces of sticky tape (on the inside) to keep the pentagonal faces together. Overall it is a pleasing construction (all be it a little cheaty)

I shall continue to look for modulars – there are lots of varying complexity – the geometry alone is reason to attempt them. This module constructs a 73ish degree angle which is a little big for a pentagon, causing a paper tension that naturally tries to spread the joints.
