This thing just fits around the buttons of the X-Touch Mini.

I modelled it in SketchUp (skp included), 3D Text as in the screenshot, painted with modeling paint.

I'm using the controller for MSFS2020 with Maarten Tamboer's great X-Touch-Mini_FS2020 (https://github.com/maartentamboer/X-Touch-Mini-FS2020).

The config file as I am using it for the default label is also included.
