Netting needle (aka netting shuttle) with openscad source

I've reimplemented TimB's Netting Needle, which is the traditional tool to make nets (fishing nets, carrying nets, rabbiting nets, etc). I like to toy around with OpenSCAD, and I thought the original was a bit rough, that's why I remade it. It's very close to the original.

The OpenSCAD source for this thing ain't purdy. But it works.

I still want to round off the tip, having a sharp point isn't necessary and only encourages curling during printing.
