Honda 13 inch wheel center cap. (blank)
Took the old 'tired' (aka beat up) full wheel covers off my Del Sol and wanted a simple cap to cover the center hole.
This cap fits the Honda 13" wheel and is a good foundation for any logo you want to add to it. I probably will play with adding stuff to this later but here's a good starting point for you if this is the sort of thing you're looking for.
Note, I printed mine in a fluorescent yellow (what I had loaded while testing the print) and in the end really liked the glowing dot look.
