I made some replacement wheel caps for my FIL's car. Nothing structural, just simple plastic press-fit caps that keep gunk from getting in. They're about 4 cm in diameter and just cover the center of the wheel. They're not full hub caps. The dealer wants $20 for one cap. Yow! I printed a couple of sets for probably less than $1.00 in filament.
