This thing was made with Tinkercad. If you have a Generation III Prius (2010-present), you can pop off the UGLY wheel covers to release the alloy beasts underneath. Except - you'll have a hole in the center of the wheel that begs for a decorative cap. This is precisely measured from the Toyota part number 42603-52110 (pictured). This has a stylized lightning bolt embossed in the top of the wheel cover. Also fits Yaris, Vios These and other center cap designs are available through Shapeways: http://www.shapeways.com/shops/bitforge?section=Prius+Wheel+Center+Caps&s=0 ATTENTION This work is licensed under the Creative Commons - Attribution - Non-Commercial license.

I'm not sure how these WILL print - I am sure that they will need support. Experimentation is in order. The dimensions are as accurate from the original part as I could get, but the diameter may need to be squidged a bit for a proper snug fit. Disclaimer- you print and use this part at your own risk.
