Parametric Powerpuffs by . Customize powerpuffs with sugar, spice, and everything nice

I came across the idea to make parametric power puff girls when I was reciting the formula. Sugar, spice, and everything nice (chemical x not included). I started thinking about changing those three variables to get all of the girls in between blossom, bubbles, and buttercup.

It was certainly a challenge to figure out what parts could be reused in each of the girls. I started by modeling buttercup, and then the others, to get my initial bounds and positioning.

Overall, I am very pleased with the result. At each stage, the girls are different. It is really fun to play with and even plugging in numbers outside of the suggested range (0-1) yields interesting results.

Unfortunately, OpenSCAD will not export my files to .STI because “the object isn’t a valid 2-manifold :(

Here is the code, which is also on GitHub:
