That's EXACTLY what happens when you build your first 3D printer - print a set of spares!
(Which might instead become the basis your second - improved - 3D printer, so you need to print some spares for that ... )
3D printing can very quickly become a self-fulfilling hobby - you never actually need to look for anything "useful" to print, because there is no shortage of tweaks and upgrades for the printer itself!
