PinePlastic Derby Car

My son (5) is in scouts and needed help in designing a pinewood derby car. I am not very good with woodworking tools, so I decided to build a model with some basic shapes that were easy enough for me to mimic on wood. The 3d printed model works with the official wheel and hub set that comes with the kit. He plays with the 3d printed model instead of the pinewood version… I don't blame him.

I have uploaded the fusion file for those parents that are also struggling and want a design that they can manipulate and make their own.
