Join a makerspace if you live near a substantial one. Mine (Protohaven in Pittsburgh) has both a CNC mill and a Morgan injection molder (a rare small injection molder good for 100s of parts), which is a nice way of exploring some tech before buying it. Even more valuable are the people who hang out at these places, who have probably done the things you’re considering.
