10 Year Old Girl Assembles a Cyborg Beast for Science Fair

[Eddie]

This is an amazing story. Thanks to Jeremy Simon, who you probably remember from other interesting stories of 3D printed hands, a 10 year old girl named Sierra has assembled a 3D printed Cyborg Beast hand for a Science Fair. Her goal is to show the world how 3D printing can benefit humans and animals. This is just what the world needs, more of... girls like Sierra, and Jeremy Simon.

I'm curious why every one, or nearly every one, of these open source hands are square - all the fingers start at the exact same point, all the fingers are the exact same length, the finger segments appear to be square too.

My guess is that we are very early in this on-going effort. And squares are easier to design around for several reasons. First, the point to measure from for an adjoining part is more obvious. And also, given this is being done on hobbyist 3D-Printers, squares (and flat surfaces) are going to adhere better to the print bed.

In time... That will change.
