I’m going to have access to a 3D printer for a few days. I know two friends who’ve used them, but it’s only been for art and figurines, or professional purposes.
Are there any other cases you can think of where a custom-printed item is better than the myriad of mass-produced plastic items?


Just some examples of things I’ve printed or plan to. Ones marked with an asterisk (*) at the end are ones I largely or entirely designed myself or plan to largely or entirely design myself. Ones marked with a plus (+) are ones that are half completed. Minuses (-) are ones I haven’t started yet but intend to.
I’m sure I’m forgetting a bunch. And the above is only the useful things and excluding the mostly art/fun items.
I have in mind to do more 3D-printing of tools. I don’t have much specifically in mind. But that custom steel strapping bender is pretty cool. Also, some of what I mentioned above is available on my Thingiverse.
