Summary

Just for the record, I have always credited Performance 3D for the original concept and said this was my rendition of their drill as it was not available for download at that time. Since I designed my version and posted it here, they have made their version available on their web site. 3Dprint.com wanted to do an article on it and I declined and pointed them to Performance 3D. So I am NOT trying to take credit for it. I only wished to share a design that I admired and which was not available for download at that time.

My rendition of a hand drill received from Performance 3D LLC
