This is a model of a stone age knapped flint hand tool. I've just ordered my first 3D printer (Solidoodle) and while I'm waiting, I was wondering what I should print first. It seemed fitting to use the most advanced method of making things to print one of the oldest known tools. I've not yet tried to print this, but I have included the original blend file as well as the STL file for easy modification. Intended to be printed in cm, should come out about 10cm (about 4") long.
