These are about 2.5" round caps for the side of the Draw-Tite hitch that I have on my Subaru Crosstrek. I believe they will fit the end of any 2.5" hitch tubing. I made these out of TPU and they seem to fit pretty well due to flexibility. These were designed to prevent insects like wasps from getting inside the hitch framing and making nests. These also prevent water from getting in the tubing and causing rust. It took about 7 hours to print with my Creality Ender 3 S1 Pro.
