I have a 2007 Ranger Polaris that, when I acquired it, was missing a cup holder on the passenger side. I don't have a use for a cup holder, so I just made a cap to put in its place. Printed it out and snapped it in place. Fins on the sides extend out a little more than they need to, which made for a tighter fit but I'm not planning on ever removing it.
