The Rock-n-Roller is a customizable toy car platform that can be decorated and remixed for a variety of applications. I've uploaded 3 stl files. The first are the wheels which I printed in marble colored PLA. Sometimes the slide rather than roll, especially on slick surfaces. Would love to see someone print them in TPU for better grip. Shoutout to Heavy Metal Groot for providing the hand model I used to decorate them. Decorations are totally optional and should be easy to cover up or remove in the CAD software of your choice. The second model is the actual car platform with wheels and minimal supports. I printed in white PLA with great success. The supported version may fuse at the bottom if printed too hot or too fast. I added and air gap to prevent this but if you have trouble printing the supported version, I provided a supportless version which allows you to add custom supports where you see fit. Can't wait to see people design new wheels, new decorations and maybe even new cabs to go on top. Only assembly necessary is attaching the wheels to the cone shaped wheel bases with a little bit of glue or putty. Anything that can attach plastic to plastic should work well.
