Replacement cap for van step floor screw

This is a 21 mm diameter cap that I designed and printed to replace ones that we lost while working on my sister's 2018 full size Transit van. I explored creating my own tessellation to mimic the textured pattern of the original cap. It worked out pretty well. The Transit van has a large plastic step at the sliding door opening. That step is held down by three or four screws that are then covered with these little pop-off caps.
