Already had one I bought months ago, but for the price, I've got two more on the way to me. I'll use one for a straight shank, one for a Morse taper #2 for my Bridgeport M head and one for a ball turning attachment for my lathe. Thanks for the heads up on these! I drew up the one I had in Fusion 360 yesterday to start doing some design work. Attached is a turn table view of it.
