Excellent! Once in a rare while I bargain hunt (flea markets / garage sale) and was super happy, a few years ago, to find a set of four Selectric balls in their (blue) case for 2 EUR. 3D printing these is next level though! Besides that I have fond memories of my father endlessly typing on his Selectric typewriter while smoking a cig (this was a thing back then).
