Amazing and Crazy 3D Printed Clear Hermit Crab Shells. Just Wow.

Holy genius idea!  THis is got to be one of the neatest things I have seen in a while.  What a fantastic idea!  My kids would go absolutely ape crazy over first getting a hermit crab (they seem kind of dirty and pinchy to me), and second having a completely crystal clear city scape on it's back.  Fantastic!
