I have a blind student in a biology class in which the class is studying the similarity of skeleton limb structures of various animals. I would like printable models of the limbs of animals. These would include the upper arm, forearm, wrist, and hand/foot for several different species of birds, quadrupeds, bipeds, and marine mammals. Ideally, I would like individually printable bones; for example, in the hand/foot I would like individually printable metacarpals, metatarsals, and phalanges, that the blind student can "put together"" to "see" how they operate and how they are similar in different types of animals. Any help in this area is greatly appreciated. Thank you.
