Two part thingy: eject_knob.stl is the main part with cutouts for the letters; eject_letters.stl is a separate file with the letters in 5 slightly different sizes so you can pick the ones that fit best for your printer. I used gray letters with black plug to fit the interior of my MR2 Spyder. Print this and ask your date to behave. (Recommended for convertibles only.
