I produced these for hanging on my beehives to identify a colony - useful for consistent record keeping. I've uploaded a blank version so different numbers can be used.
Using your favourite gcode generation programme combine the relevant title and number to the blank label plate to generate the relevant gcode file for printing. The reason I keep the text and number separate from the label plate is so I can I print the text in a different PLA color to the base label plate which works well.
Using the Sketch project you can use the 3D text plugin to generate different text.
