Chair foot, replacement

My little kids folding lawn chair was missing the plastic caps for the feet, so the chair would sink into the ground. So, of course, this called out for a replacement printed on my Thing-o-matic in just a few minutes. This is designed specifically for the smallish 13.6mm diameter metal chair legs....probably not a standard size.

If I knew more, I could make it parametric or customizable in size, but for now, the downloadable STL is specific to this leg size.
