Instead of having to pay a fortune for a piece of plastic, I designed my own wheel nut caps to hide the standard wheel nuts on my car.

They are designed for 17mm wheel nuts and are gently pressure fitted onto the nut itself. To remove it, it's recommended to use a generic tool for these caps, or you can carefully lift them off using 1 or 2 screwdrivers, using the extending top edge.

It is also recommended to try it on a loose wheel nut first as tolerances can vary between them and tolerances in printing can cause them to get stuck, making removal difficult. 

The model is best printed in the original orientation. Examples were printed with a 0.4mm nozzle at 0.2mm layer height.
