About this 3D model

So, to get the best hex nut capture socket fit, I wrote a parametric OpenSCAD script to produce a simple test part. Any screw size with either a hex head or a round capped head can be configured to produce a test part for 3d printing. Use the Thingiverse Customizer to produce custom STL files. The project with variable setting details are published here:http://airtripper.com/1594/hex-nut-capture-socket-sizing-for-3d-printing
