Put your name on a clicky snack counter. Type it in, check the preview, and download a 3MF or an STL. The lettering is raised 0.8 mm and prints face-down on the bed.
Same set as the original print: both dials, both springs, and front and back plates for variants A and B. 3MF keeps the lettering as its own part on each front plate. STL is one mesh of those same parts.
Lettering occupies the first 0.8 mm. With 0.2 mm layers, add a filament change at 0.8 mm and the letters come out in the first colour. Print the front plates on their own if
you do this.
Long names shrink to fit the plate. Below about 1.8 mm tall, letters get mushy on a 0.4 mm
nozzle, so try a nickname or a shorter tagline.
