A simple print in place without support and parametric wall mount support for your remote.
This model was created using freecad an opensource and free CAD software.
I've included an .stl as an example but I encourage you instead to customize the model for the size of your remote.
I won't give you a course on how to use freecad but here is more or less a guide
instruction for customization :
enjoy :)
