Option 2 will require you to change the nozzle on your 3D printer.Option 1: Print the keyboard keys in WHITE PLA using standard 0.4mm nozzle and color the characters with a black marker. This is easiest to execute and cheapest. This is how is being done in the YouTube video above. Most people will use this option.--------------------------------------------------------------------------------------------------Option 2: Print the keys in black PLA and the character layer in bright color like yellow or white. 3D Printer 0.2 mm Nozzle gives a very optimal result. I want to give credit to “darkextratoasty” in Meshtastic discord group because he gave this idea. This is recommended for people who are comfortable switching out their 3D printer nozzle from 0.4mm to 0.2mm and play around with your slicing software. -----------------------------Go for Option 1 for the keyboard if you are not sure where to start because you can use the standard 0.4mm nozzle on your 3D Printer
