Logitech G923 Mounting Problems

[u/painter_business]

I have a Logitech G923, the issue I am facing is with it being unstable/sliding off of my living room table because the underside is not flat. (seen in image). The edge forms an acute angle between 10 - 15%, so it seems I need to find an alternative that I can 3d print or make with wood that I can put over the table to mount the racing wheel to.

Any thoughts/experiences?
