Mask hook

Customizable mask hook. If the customizer of Thingiverse doesn't work, use [OpenSCAD](http://openscad.org) directly. [Hello, OpenSCAD!](https://openhome.cc/eGossip/OpenSCAD/HelloOpenSCAD.html) provides a basic tutorial about using OpenSCAD.

The source code requires [OpenSCAD](http://openscad.org). It can be found on [dotSCAD/examples/mask_hook.scad](https://github.com/JustinSDK/dotSCAD/blob/master/examples/mask_hook.scad), too.
