Snap fit joint/connector

My daughter asked me if I could print a chair big enough for her to sit in.

Challenge accepted. See http://www.thingiverse.com/thing:218782

To do it, I had to design this snap fit joint for the legs and posts. I thought people might be interested in the joint itself to play with. If I start using this more often or if there's interest, I might clean up the OpenSCAD code and turn it into an easy to use library.

FYI, my daughter loved the chair, but quickly grew out if it. Now she uses it
