Also inspired by http://www.thingiverse.com/thing:1600741 parametric holder, this script generates the parts for the Soma Cube puzzle pieces of similar size (30x30x30 mm).

TODO:
-Refactor the repetative code
-Generate the other puzzles
-Write a generator for all possible puzzles

This is an untested work in progress because I have to go to work now :(. You may have to tweak the size to use this part with the original .stl files
