makeThreadTap script

 From:  Martin (MARTIN3D)
The attached script makes an internal thread cutting object a.k.a tap.

Enter the thread length longer than required.

The lower portion can be used to Boolean Diff a clearance hole. Hide the thread tap and chamfer the hole.

A second Boolean Diff with the upper part of the thread tap and "Keep objects" unchecked finally cuts the thread.

Update: Cancel button works now
