This is the first thing I wanted to build and share.
bottomless-cup-just_cup-11-16-2018.stl - fits the "trenta" cold cup sizes at your local coffee corporation. It's meant as a replacement for the paper sleeve, and to make a to-go coffee held like you're sitting at your desk.
Cheers and thanks for all the sharing here!
