For the final design, I made a lot of changes and additions to the car's design. The first change is the two side panels attach to the side now rather than the top of the car and there is a new piece going across the top for structural support. In addition to that, there are now half inch straws used for spacers on the axels. Finally, there are balloons around the two rear wheels to add much need grip and made the holes on the car for the axels larger along with a slot for the rubber band.
This whole process has taken a lot longer than expected and I changed almost the whole design in the last week. I wanted the whole car to be able to be just cardboard but that proved to be impossible with the small design I was going for; however, I was still able to avoid the use of glue and tape. I learned better ways of troubleshooting design and overall efficiency. Next project I should be more efficient and more resourceful. Here are the instructions, materials, and Adobe Illustrator file.
I have a made a cheap and effective press fit rubber band car. Twenty cars cost about twenty dollars, meaning that one car cost about one dollar. One car only needs one piece of cardboard and it take about ten to twenty minutes (the pieces connecting the wheels can be a bit finicky). I made my goal of a small and quick build of a rubber band car not using glue or tape; however, I tried to make it almost one hundred percent cardboard, in the beginning, I was unable to make it practically but the principle is still the same.
