As requested by some folks in the community. Here is my button box mount for the Pro Switch Panel and Stream deck. If you would like to build one here are the components.

Pro switch panel from Precision Sim Engineering

The stream deck. MUST BE MK.2

10X M3 bolts and you need an M3 tap.

Important note. The order to layer everything is Button panel, aluminum back panel, then 3D print. There is a space made for the mounting arm.

If you would like this on the left side of your rig simply mirror the model and you're all set.

Happy Racing!
