Forstner drill bit guide

Simple guide for Forstner bit. I designed it for an Irwin 3/4" bit with a 3/8" shank for standard hand drill use. The depression in the top is for gluing in a fender washer to prevent bit chatter from ovalizing the hole.

I included both the STL for slicing, and a *.sat file for modifications (for other bits, etc)
