RIEC - 3D Printed Wood Filament Puzzle

RIEC (Rotating Interlocking Edge Cube) is part of a series of Edge Connected Turning Interlocking Cube (ECTIC) puzzles.  

RIEC is 3D printed puzzle using a premium wood 'Sandal Wood' infused filament.  The resulting color is an earth tone brown, though not exactly 'wood' looking.  The puzzle is quite a bit larger and much stiffer than my normal prints.  The hope was to bridge a little of the gap between my normal 3D printed puzzles and the very expensive true exotic wood puzzles.  Though these filaments are much more expensive and very difficult to work with, I believe the result is quite good. 

Rotations are required to solve the puzzle!  However do not force any rotations!  The intended solution will rotate easily with no more force than what is required to overcome friction or through bending the pieces. It will ship disassembled.  This puzzles was created with my new re-enforced joints (printed in a different orientation to ensure strength at the joint).  The puzzle should still be treated with care and not by forcing any movements.  These puzzles are not intended for children.
