Tetra-Hedra Building Blocks!

Years ago in college I took a sculpture/3D Construction type Art class. One of the projects was to make a kind of Unit - a 3D shape out of like paper, or cardboard or such. But, make MANY of them. Then, take all those pieces and create a sculpture with it. Too bad I lost that sculpture over the years.

So - I've been wanting to do something like this via 3D Printing. Then, recently when browsing on Thingiverse here - I came across the Customizer App that allowed you to create geometric shapes. As such, it was the PERFECT Starting point. I created the TetraHedra. But, I then took it - and split the sides of each leg. Then - on 2 sides I pushed it outwards - and 2 sides are pushed Inwards. Thus - 2 Tetras will fit together!

I also decided to make the initial ones BIG - so once I 3D Print a BUNCH of them - I could assemble together and make a REALLY Big Sculpture!

My buddy "JetGuy" said - to build a Temporary structure - to plan a sculpture - use Hot Glue gun to put pieces t
