Ken applications .... OpenSCAD version used 2019.05

This is another openSCAD file which lets you customize your own knurled nut.
It does not use any library files only a few modules which you can use in your own projects.
I have only tested it on an M10 X 1.5mm thread and included a 0.4mm tolerance in the thread module which made a perfect fit on my Ender 3 pro.
the Knurl module that i have used comes from https://www.thingiverse.com/thing:3673637 (Big thank you for this)

Render time took about 1.5 minutes.
Print time about 12 minutes for M10 x 1.5 thread with knurled outside diameter of 20mm
