I almost always have my flexible axle on my Dremel and needed some way to fix my Dremel in place instead of it just lying around.

Only 2 changes from the source are the removal of the threadding to Mount the Dremel and some enlargement to make room for the Mount-piece of the flexible axle.

Attached the Dremel using a couple of zip-ties. You can use all the adjustment stuff from the source as I retained all his nice options.
