The sticker on my pool pump had faded so you couldn't read the positions. A replacement sticker is about $15 and they don't last long so I made this one. It's drawn 1mm thick with 1mm raised lettering but you can scale it to 60% in Z axis and it comes out exactly three layers of 0.2mm each. Change filament after layer 3 (or after 5 if you make it 1mm thick) to a contrasting colour. This one's PLA (all I had at the time) but for durability ABS or PETG might be better.
