This is a quick screw on attachment to turn your Dremal into a very simple drill press using a 2" piece of PVC pipe. I'm not sure what the threads are I just matched them to my Dremal. If it's to loose in the pipe to be accurate enough you can wrap a layer or two of packing tape around the attachment.
Note- The attachment has to be unscrewed a bit to access the chuck lock button.
These parts were used on my custom built computer desk seen here http://imgur.com/a/d5D1j after sharing my project on Reddit 3D Printing I received a few requests for the files so here you go guys....Enjoy.
