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?


I generally come across specific things that prompt me to print a custom solution for my life. I wouldn’t be surprised if there literally isn’t any truly useful better-3d-printed-than-purchased thing that someone can recommend for you. (But maybe I’m just not imaginative enough :))
Maybe the biggest category of things is replacement parts for stuff around your house. The $7 doohickey might cost you $1+time to print instead.
That said, here are some things I’ve printed for use around my house, which might give you some ideas for your own life:

A couple examples of the concept
Cool, thank you! Based on that I also found it on Wikipedia: https://en.wikipedia.org/wiki/5S\_(methodology)
