About this 3D model

This is an attachment for a dremel or similar tool that makes it easy to grind tungsten electrodes for TIG welding. It has holes for 1/16", 3/32" and 1/8" electrodes at 4 different angles. It uses a diamond disc that I got at harbor freight (I think) Thanks to Lenbok ( http://www.thingiverse.com/Lenbok ) for the original design. I'd been meaning to design this for a while but his design did most of the work for me.
