Description
Technically you can probably call it a rounded isosceles trapezoid but it will be more useful as a base for path of bicycle chains or pulley belts. When both radii are the same and spline set to renderable, it could also be used as a simple chain link.

Additional Info
Note: Holding shift constrains the created shape to X/Y view axis. Both radii can be locked in the UI to be the same.
Installation: Copy the .ms file to your scripts\startup folder or run as a script if you want to try it out first. The object primitive will be available under Shapes -> Examples dropdown menu in the Create panel.
