A very simple graduation cap. I added a hole on the top in the center for people to add tassels. I rounded the corner because after 4 years of grueling hard work, nobody should lose an eye, plastic caps are HARD.
I based the dimensions off of http://en.wikipedia.org/wiki/Human_head#mediaviewer/File:HeadAnthropometry.JPG
looking at the 50th percentile.
