When I got my G-pen in the mail I thought I'd be getting a G-Card grinder with it. I was disappointed when I found out I didn't. So I thought I'd try Thingiverse before throwing down a few extra $$.. Found this wonderful design by RenatoT, and modified it so it had the Grenco Science Logo to match the pen.
(also modified one of Wsteins containers to match as well. Can be found here: http://www.thingiverse.com/thing:647633 )
If the side with the logo gets stuck, Don't twist to remove! That's how mine got ripped off. Make sure you use it on something like grass first to make sure you aren't grinding up any plastic into your herbs. Stay safe and happy vaping!
