My son printed me the case and bought the electronic parts for a portable M12 pinecil power supply. Its pretty slick for small electronic parts soldering like guitar pots and pickups and other odds and ends.
He also printed a tabletop smoking pipe holder and various pipe stems. Also 2 wireless internet child nodes wall mounts and a corner wall mount for a child node. Gets them off tables freeing up space.
So now I know what to get him for Christmas. He and his buddy use his dads Prusa printers. I had no idea useful stuff was being created with this.
