Tumbling Toy ! (Customizable)

Didn't you make toys like this at least once by cutting paper when you were young?It was fun, and suddenly I wanted to make this again :) Instead of crookedly cut paper,now that we have 3D printers, we should make it look much cooler :) It seems like something fun to enjoy with your child.Or you could have a drinking game with friends to see who can send it the farthest. Since we're making it with plastic this time,please use steel balls instead of glass marbles.I've prepared various preset profiles for the sizes of steel balls commonly found on Amazon.The profiles have auto-pause enabled.When printing pauses, drop the steel ball inside and press “Resume Print”. and one more thing.This toy rolls down an inclined surface.It does not roll on a flat surface. Although it's a parametric model,there are few things to cover due to MakerWorld's feature limitations.If you won't be using the preset profiles, please read the following details carefully. 1.
