Anyone print anything useful beyond little trinkets/figurines/toys?

Hi all,

I live on a boat and have been going back and forth for a number of years thinking about getting a printer. I never pulled the trigger mainly due to the fact that everything I've seen from a printer has been basically useless crap that functionally isnt anything more than something to sit on a desk and say 'oo ahh'. Sure there's helmets, and cosplay stuff but that's not like something that is highly useful.

I am likely to be getting a printer in the next month - itll probably be a A1 mini or the P1S if I can fit it in the space. I have a number of things for my boat that could be printed and honestly it's far easier doing CAD work and printing something to spec than machining down HDPE or wood by hand to get 'the perfect fit'

I've seen a book stand light as well as a shelf that was pretty good and useful, pen holders are useful, but beyond that how many shelves, and pen holders do you need?

Does anyone use their printer for things beyond toys? Would absolutely love for people to share what they print(photos welcome!)
