Anybody know where or have a STL file for this, or can make one?
Looks like whoever created it would have the STL. I haven’t seen a design similar to it so I would guess they are holding into it since it’s their IP.
That said, playing with 3d design can be a fun project. You could maybe design a more simple unit and have it printed via shapeways or any of the other 3d printing marketplaces.
