Sharpie Holder for Shapeoko 2

Sharpie holder I designed to fit on the standard spindle mount that comes with the Shapeoko 2. I needed a holder that was a bit more sturdy so I designed it to utilize all four mount holes and to extend out past the bottom mount. Will have to use shorter bolts instead of the extra long ones that are used for normal mounting of the spindle. Feel free to contact me with any comments, concerns, or questions. Thanks for looking =)
