Anyone aware of a merch service, like Redbubble or Teespring, but for making pins/badges?

Ever since I started doing those vignette illustrations based on my favorite games, I've wondered if I could do little badges also based on videogames I really like. Mostly for myself, so that I could basically have Pokémon Gym-style badges, that I could pin to a cushioned frame and hang on my wall. But if people were to be interested, I could maybe put those up for sale.
