Description
UPDATE: I decided to tweak the dimensions of the cup a bit to better suit the application. See my new soft top and cup here: https://www.thingiverse.com/thing:4572018
So I printed John Mulac's Collapsible Cup as a fun test print after rebuilding my Prusa Mk3S extruder assembly. It's a really great model and when I pressed his cup firmly open it even held water for me. I mean, I wouldn't want to leave water in it overnight, but it was definitely a usable cup.
From there it was sort of a part seeking a purpose. That is, until I saw my daughter's snack cup and thought, hmm I could make a soft top for this and make it a snack cup too. It works great for dry snacks and collapses nice and small to fit in out diaper bag. Nice.

Enjoy!
