Field Notes Clip for Blackwing 602 Pencil

Hello pencil nerds! This is inspired by the original Field Notes Pen Clip, but I've recreated the design in openSCAD to work with a Palomino Blackwing 602 pencil. The Blackwing 602 is a reissue of the legendary Eberhard & Faber Blackwing 602 http://en.wikipedia.org/wiki/Blackwing_602

I've included the openSCAD file so you can play around with it and make it fit any other pencil, like maybe the Dixon Ticonderoga 1388-2.
