Reusable collapsible coffee carrier

thingiverse

I regularly fetch coffee for my wife and me, they used to offer decent cardboard carriers, but now they only provide those terrible ones that stick into the bottom of the cup. They feel unstable, and for two cups are not much better than carrying two cups separately. So I decided to create a reusable carrier that I could easily fit in my bag when it's flat, but quickly set up when needed. The handle prints in place with integral pivot points, allowing me to insert it into the central cutouts in two different orientations. One orientation keeps it mostly flat, while the other holds it securely for carrying. Hopefully, the pictures demonstrate what I mean. So far, I've found that it works great with Costa's paper cups as well as their reusable cup, and a smaller glass 'KeepCup'. It obviously requires a cup with tapered sides, we do have one reusable cup with straight walls which doesn't work with this design.
