Vive Breakout Box Suction Cup Mount

I have a glass desk and wanted to mount the Vive breakout box to the underside of it so it wasn't just flopping around when I yanked on the cord so I decided to design my own. It's pretty straight forward and designed for 30 mm suction cups or less. The link to the ones I bought and sized it for are below.
