The Remix thing by Thingiverse doesn't seem to work. If you have large hands, try this : (https://www.thingiverse.com/thing:4298985). I don't like how hard it is to get in and out, and it's too big for me. My first version was smaller, and can still fit in a pocket, but isn't as comfortable. Both grips have a lot of play so you can put some padding in there to prevent scratches. I printed them laying down with supports everywhere and ironing for smooth top surfaces. I'm open to any suggestions.
