I enjoy an iced tea with crushed ice now and then, but I don’t want to use single-use straws to prevent the inevitable slurping sounds that’d disrupt a quiet office.
Yesterday, I designed and printed out this scoop cup I call SCUP Version 1.0.

Scary language over.

I specified a minimum of 3 layers of PLA, ran it at a 35% fill density, and, for extra security, sealed the inner surface by melting it a tiny bit with a solvent (to let it evaporate before suing).

It keeps the ice away, and is easy to use and clean: I drew a large radius between the bottom of the SCUP and the sides, so that one could clean it without straining one's hands.

I just tried it out at my local watering hole and it works great! Your results may vary. Have some fun with this.
