This is a human femur (right side)that was created from a real bone. Not quite sure about who it was (male vs female, height, etc.). I used a NextEngine 3D scanner and patched together the images in order to make this.
I have made this full size on a dimension sst 1200es using ABS and their support material. I have also made this on a cupcake, obviously not to scale. So have fun making your own tiny skeletons. I am working on tracking down more bones in order to scan, but it is very time consuming.
The file labelled with Makerbot, is rotated and scaled for a Makerbot
