Rental Key Fob

My son owns a duplex and he needed a way to keep the master key sets organized and separate. I designed a blank in Blender and then added numbers as shown in the photos. He used a Sharpie to write additional stuff on the back. I subsequently printed several blanks for friends and neighbors who just used a sharpie to label them.

This is such a simple model I'm almost embarrassed to submit it, but I've never entered a contest before, so…

Thanks for looking.
