I'm sure there are some if random videos from YT don't do it for you. What I did was just browse makerworld and thingiverse favoriting things I'd like to try printing then keep the printer as busy as possible for a couple weeks getting through my favs. The way it works for me is I get immersed in 3d printing and lots of ideas come which sometimes leads to modeling and creating revisions until I'm happy with it. Just print what seems fun and ride the wave!
