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?


Where a 3D printer really comes in useful is when you learn to model the things you need yourself, things that simply aren’t available as mass-produced products.
