link with holepattern, customizable

This is an OpenSCAD file that can make a rounded end boss with holes or pins,

It was mostly an experiment with an array pattern aimed at a boss to fit a certain mechanical part, but you can use it make wheels, link-pins, etc...

If the boss has the the width equal to the length, it makes a disk. If the lenght is less than the width, it degenerates an dissapears

The pattern can be of holes or pins, with customizable numbers and spacing
