This is the Multidodecahedron. A puzzle that has all the parts from the Megaminx, Pyraminx Crystal, Starminx, Master Pentultimate and Pentultimate and requires you to solve them simultaneously. This puzzle was initially suggested by Carl Hoff, who coined the name Multidodecahedron.
If you order this model, you will get a DIY kit of the plastic parts needed to make this puzzle. You will need to supply your own screws (M3), stickers and springs for assembly.
You can also order an assembled copy of this puzzle from me directly, but this option is more expensive and it will take longer to get your puzzle.
Shapeways has recently changed their pricing making this model much more expensive. I've not yet had the time to optimize this model to be as cheap as posible. Please contact me at firstname.lastname@example.org if you are interested in obtaining this puzzle so we can discuss cheaper options.
