This completely redesigned version comes with a new set of flat teeth, color change file, or the origial sharp set in single color. Also new updated number font that is easier to print and assemble. New magnetic lid. 4x2mm magnets and new tongue that prints faster. The mimic dice opens up to double as a dice tower. You can also collapse it down to use as storage. Parts can be printed separately for easy color swapping. The flatter teeth with gums are a color changing file. Please watch assembly video! I do recommend supports on the outer shells and inside mouthpieces. But the tongue, neck, and teeth do not need any supports.
