So this is a gimbaled to-go coffee cup holder. 

Fully 3d printed, assembly is just spin the bolt in.

Designed to clamp a bar 20-30mm in diameter, as well as flatter things, like dashboards, etc. The diameter should fit a large double walled cup or similar, but there's an adapter to fit other things if required.

Print settings as you like, recommend 4 perimeters, but don't use supports on the gimbal section. Gentle working back and forth will click the joints loose.

Let me know how it works! I can tweak things(the bolt is already tweaked from the pics), or the .step & .f3d files are here, so make it fit your world.
