LEGO launcher in OpenSCAD

This is a simple lever and fulcrum that, combined with LEGO minifigures and children, turns into a catapult. Inspired by the "Made by Joel" website. http://madebyjoel.com/2012/05/small-catapult-toy.html

Also, an opportunity to experiment with laser-cut parts in OpenSCAD, and to test laser-cutter offsets for press-fit peg-joints.
