About this 3D model
This is an under desk mount for the Tsupy USB 3.0 hub. It was designed a few years ago, but it's still actively for sale at Amazon and other retailers; so I'm hopeful it may be helpful to others out there that are looking to do the same thing as I was, mounting a fingerprint reader. I have the front and rear, but also included the open frame, but just be aware that if you use that the tolerance is fairly loose so it won't directly hold the USB hub with friction alone.
