M12 Brushless Rotary Tool Screw Chamfer Attachment

This attachment replaces the collar on the M12 Brushless Rotary Tool when you've got a cut off screw you want chamfered to clean up the threads. It locks into the same quarter turn bayonet coupler that the regular collar uses. You'll need to use a wrench to tighten down the collet nut, but the attachment will fit over the standard rotary tool sandpaper drums so you can attach the drum before or after installing the attachment. I designed in inches, you may need to scale by 2540% in your slicer.
