Yeti Rambler Cupholder

I just needed a cupholder for these BIG Yeti rambler cups in the car.

So I got my micrometer out and did some measurements and made one in tinker CAD. 

8 versions later I have a working cupholder!

I made mine at 15% infill for speed of printing but feel free to kick it up to more if you need it to be stronger.

Enjoy!
