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?
check your library! a lot are adding maker spaces. My local library has a couple 3D printers, laser cutter/engraver, cnc vinyl cutters and all sorts of handheld implements.
