Here is a model for 2" hitch cover with a camper on it. I have a teardrop camper and wanted something personalized. I used to sell these on Etsy but stopped a while ago since my old printer broke. Will add them again, but thought I'd share it here.

I print these out of PLA, and have had no issue. Mine has been on my camper for over 3 years now with no issues. I'm also not in extreme heat conditions.
