Mini Floor Stand - OpenSCAD (fixed arm support)

This is a remix of https://www.printables.com/model/263710-mini-floor-stands-openscad-remix-of-muzz64s-design where I modified the OpenSCAD code to have the notch of the support arm point downwards instead of upwards, and redesigned the arm lock hole for a more snug fit with the support arm. This way, the support arm is held in place by gravity.

If the arm won't fit through the hole, adjust the armLockHoleLipHeightAdjustment variable (lowering it will lower the lip and increase the clearance).

Also provided a blank STL generated from the Scad file, for those who don't have OpenSCAD and just want to add text via the slicer.
