I’d go with Uriel’s and Aisha’s ideas: Operation Magic School Bus is definitely a win-win for donations, and as Aisha said supporting players or groups who support EVE is another win-win.
Mike’s Magic Bus, EVE University, Youtubers, people who run 3rd party services or website resources that you feel are worthy, in-game groups who help bring new players into the game, all of these can use your stuff. I often turn excess ‘stuff’ into ISK and then donate it to some player or group who’s doing something interesting.
In the past I’ve also donated ISK to EVE Pandora for them to set up player campaigns with (although they actually prefer players to do those themselves).
Of course check in with anybody you think of first, to make sure they’re available to accept contracts etc.
Best of luck with your next hobby!
