I have a small workshop with limited space, with all the little projects I like to do, i'm often using a computer for reference. To that end I've mounted a small screen on the wall, and mounted a laptop underneath my work surface. It's paired with a small wireless keyboard/mouse combo. This allows me to save space and keeps the laptop from getting covered in saw dust/dirt/metal shavings/glue/etc.
They're simple 'S' brackets with 2 screw holes.
I printed in PLA with 4 walls and 20% infill. Mounted with 1" #8 wood screws.
