I think that’s a bit of a negative viewpoint. Here’s another approach: I have a 3-D printer. I don’t need to justify the fact that I have it. I use it daily, most often multiple times a day, both personally and professionally. It’s always here and always available, I always have filament for it, and it can produce a cap much faster than getting one shipped to me since I live rurally and there’s nowhere local to buy one. Why shouldn’t I simply print one since I already have the printer?
