Starship drinking cup

A protracted search yielded no new drinking cups as good as what we had 25 years ago.  They're all prone to falling over because they're tapered on the bottom.  Lions had a tapered cup from 1995-2000 & it always fell over.  They're also not as big as what we used to have.  Lions got to thinking the stability could be overcome by epoxying a base to the cup.  Then, what a lot of animals are doing is selling a wrapper for an existing chinese cup.

Only an idiot would burn $50 on that.  It's pretty low effort, just a low fidelity engine base stuck to a common steel cup.   The next step up would be a V3 wrapper for a tapered cup.

A completely PLA cup would be quite difficult.  It leaks.  It degrades.  It's more expensive than a common chinese cup lining a wrapper.

The current 50 cent Targ cup is smaller than the $1 cup 25 years ago.  The next step would be super expensive thermoses/tumblers.
