Balloon car

This is a balloon car my son and i built for his school project.

I believe these are the wheels and pegs we printed with it but you may have to do some tweaking. Other than that potential issue this car worked very well and got him an A. Very fast! Just add balloon!

**Updated car body to version 3 (increase size by 150%) as per the suggestion by user CrazyCrow

**Uploaded STL of wheels and pegs per request
