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?
There are a lot of minor things, that are much faster to print than to get delivered. (If you can find them at a sensible price).
