This is a complete redesign of https://www.thingiverse.com/thing:4086745. I removed the phone holder and changed the design to make it printable without support.
This hooks onto any standard shopping cart (The larger version works on Costco carts) and holds multiple cup sizes. It collapses to fit into your pocket by sliding the bottom plate up and folding the leg.
A dab of Loctite on the screws will keep them from working themselves loose when you fold the leg.
Parts: Two M3 x 8mm screws with hex nuts
