Ok players hear me out, I want to be a cool dad.
I'm tasked with giving a party of teenagers something cool for their ttrpg fantasy game.

What's something that the whole party can use/enjoy, something else that's not food, dice and personal miniatures?
Cup holders? Is there are some fidgety stuff you like to do as player while waiting out?
What's something that you as a player would like to have as an extra, on the table?
Something with good reusability, something you use a lot, may also not be something for you as a player but rather for the whole party as characters? Maybe a pet mini for the party?
Post me what YOU would like anon

Tl;dr: Gave the DM a battlemat, I'm looking for something to give to the players that's not food, dice and miniatures. Have a 3d printer and crafting skills.
