This!! It's also given me a lot of insight into industrial design. As in how do you make something strong in the right places yet not use too much material. I'd seen the result of such choices when opening up devices but the "why" never sank in. Obviously this is not a super important thing in the scope of our world and my day job. But still, it feeds my curiosity (as does this site) and that alone is more than worth the investment to me. Also, being able to design and manufacture a plastic part in a matter of hours any time of day or night has become a really useful tool. Only a few days ago the window latch on the front door of our apartment broke off and we've already had too many break-ins. It was too late in the day to go buy a new one but the printed one works really nicely.
