Parametric Golf Tee, Spike, Pin generator

This was my first crack at an OpenSCAD file. I started out just making a very plain spike, and it evolved a little. Strangely, I don't play golf. But my brother does, and it makes a nice tee.

Good for all sorts of spikes, pins and golf tees.

I've included the OpenSCAD .json file for the settings for the provided models.
