Hexsticks - STC #25-C

Four Color Hexsticks - STC # 25-C 

A 12 piece puzzle with all pieces tangent to a face of a rhombic dodecahedron.

There are 3 solutions to this puzzle (photographs included):

1.  No two like colored pieces are parallel to each other.
2.  All pieces parallel to each other are the same color.
3. No two pieces parallel to each other are of like color, and no three like colored pieces form a star.

I also supplied a single STL containing all pieces to create a puzzle in a single color.  

The pieces are 4" long and 1" diameter (to the flat faces).  The OpenSCAD program has adjustable parameters for scale, piece length and diameter.
