I actually cut those parts out of the main print and had them printed in an resin printer, then made a slurry of acetone and talc to glue and hide the seam. Worked really good.
That will be the best approach. Although I may give it a try with a 0.2 mm nozzle and printing the text inserts horizontal with 0.04mm layer height as I don't have access to an SLA printer.
