Please see my reason for making this thing here: http://www.thingiverse.com/thing:16662I need the tap holder for rethreading holes after powder painting. That is why i made the handle thicker. For a drill holder it might be better with a thinner handle. Let me know if you want me to make one :) The insert is drawn with a Ø6,1 hole. I will also change that for you if needed.INFO: I have measured some other taps at work today. They do not match the size of the cheap ones I use at home. So please check if the ones here will match your tap.I will post new inserts soon.Print parts Clean up if needed (I ran a drill through the insert) Assemble the holder
