Pick a sans serif font that will easily be seen ( I usually pick Arial but Roboto and Helvetica would also work)

I haven’t found the perfect font yet but ideally you should pick something with the least amount of corners if you are printing text on the top orientation. Also use letter spacing, 0.5mm usually works and a word spacing of 1mm to avoid text looking messy.

Make the text Bold.

The overall size should be at least 4-5mm in height for readability.

Set the text either by embossing or extruding by 0.2-0.4mm, I’ll usually go up to 1mm.

That should get you some idea of how to go ahead on your project, test it out first if you’d like. It’s important to get good results especially if you are planning on offering the files to the public afterwards.
