I use a Prusa MK2.5s with a 0.4mm nozzle most of the time. For fine detailed legends I use a 0.25mm nozzle. Here's some keycaps I printed recently: https://imgur.com/a/Ge0tlc5 https://imgur.com/a/Ge0tlc5 The key (haha) to printing great keycaps is to print them on their sides. That way their top surface is smooth (to your fingers) right off the printer. The keycaps in those images have not been post-processed in any way. That's exactly how they looked when I took them off the printer.
