Grinder attachment

I printed a few of the grinders on Thingiverse and didn't like them and my old hands have a hard time gripping my grinder these days so I made this to fit over the top of my trusty grinder. Then I stick the end in my drill and grind away on slow speed. Dunno if anyone would want this cause it's made to the size of my grinder but who knows, if it helps you out then I have done my duty. Enjoy
