Logo spinner for pickup truck wheels

My nephew asked me to work on something that would allow him to put a logo on the center of his hubs  that would allow the logo to stay still while he drives. This is my first attempt and is in the process of being tested. 

My nephew will be working on an install video for this soon. 

If you seen anything else that should be added or you thing would make it better let me know. 

Standard bearings and tire weights are used in the insert sections of the print. 

No supports need to be used.
