Remixed the great model from UnimatrixRed.

• Gears trimmed by .64mm for easier assembly
• Center windows painted for multi-color
• Center windows use Concentric top layer for appearance

Assembly:

1. Insert gear A into core half 1 with the gear "notch" aligned to any point of the triangle on the outside of the core half.
2. Press a corner pyramid on to the gear shaft. This will help keep the gear in the correct position during assembly.
3. Work around the core half with remaining 3 gears, alternating gear types A & B. The same gear types should never touch each other.
   • Core half 1 has a recess for a 6x2mm magnet. Be sure to use the corner pyramid with the matching magnet recess in this location.
4. Repeat steps 1-3 with core half 2.
5. Glue magnets into core half 1 and matching pyramid.
6. When you've verified that each core half works smoothly, glue triangle windows to the core and then the pyramids to the gear shafts.
7. Glue the 4 alignment pegs into one completed core half.
8. Place the second completed core half together with the first, using the pegs for alignment.
   • If the pyramids are not aligned, rotate one core half by 90 degrees and re-assemble.
9. Glue the core halves together with the pegs.
10. Glue the pyramid windows, center windows, and frame windows into place.
