Classic Rocket - Launcher

My co-worker printed a *ton* of these rockets to test filament and slicer settings. I figured that they needed some kind of structure to organize them.

Also my first programmatic OpenSCAD drawing - enter the number of rows and columns you want to print. You can also print a taller version or a short version.

I've included 1x4 and 2x2 short version STL files.
