Kudos to @mattlang and @wmealing for the inspirations: https://www.thingiverse.com/thing:782152 and https://www.thingiverse.com/thing:1696315

Decided to take the opportunity to learn some OpenSCAD and turn this into a customizer from scratch!

Practically every dimension of this is customizable, however I think most people just want to adjust the table/desk thickness, the clip tension, and the coil diameter, which are the first options. I also added a small divot for a Glue Dot to help it stay in place on a desk's top. You can easily turn this off by setting this option to "0".
