Simple Parametric Card Shuffler

Wanted a simple way to shuffle the cards that is also portable and fits in my Exploding Kittens game box. The model is parametric and you can customize the dimensions of the teeth or any length. As seen in the first picture you basically pick up the top stack of cards that is separated and just combine it by placing it at the bottom of the deck. You can then repeat the process.
