Why should you have to live with what your given? Print out your own xbox controller buttons in your favorite color! After printing a quick dunk in acetone or a little buffing will smooth out the top. Or better yet use some sugru to fill the letters and ad some color!
Print with any amount of fill to your taste, heavier buttons feel great, any layer height is good but the finer the better. They print in 12 minutes on Medium with a Replicator 2. Enjoy!
