I asked 3D printing Youtubers: What is their favorite functional 3D printing?

One of my goals is to promote functional 3D printing too. Don't get me wrong, I like printing toys and figures (that's fun too), but printing functional parts gives another level to our 3D printer. I asked 3D printing YouTubers for a video of about half a minute in length, showcasing their favorite functional 3D-printed creation(s).
NEW! POLYMAKER offered 2x$100 filament vouchers for the participants from the second part (by community)! More info down.


(Dear Patreons, I contacted everybody You suggested, but as you can see, the reply was only 15%)
