SEGA (JVC) WonderMega button bezel/ring

thingiverse

If you, like my friend, somehow got the plastic ring around your power or reset buttons go missing (either by your own destruction, or because it was mishandled by the postal service [looking at you DHL]), I got you covered! Just print it facing down, and give it a decent layer quality like 0.2 or 0.12mm. You might wanna sand and paint it though afterwards, so it matches the case, but it should be a snap-fit otherwise.
