Swing Arm Magnifying Lamp Mount

This is my solution for getting my new swing arm magnifying desk lamp attached to my workbench.   This required putting a hole in my bench top.   I used only a 19.05mm (¾") hole in my test and it works fine.  This was designed in Openscad, customizer available.

All measurements should be in the variables in the .scad file, I have not tried any other desk hole sizes (mount size increases based on hole size) besides 25.4mm (1").  This uses the BOSL2 library for the threads (https://github.com/BelfrySCAD/BOSL2). 

STL files are for two sizes I tried, but can include more if someone requests.

Prints without supports.
