Here's a bracket I created to mount an on/off switch for my Rasberry Pi 3 console build. I needed a way to keep the power supply switch on the outside of the case, like the old PS2 power switch. This allowed me to mount the switch on the back of the console while still keeping the power cord hidden and secure. I printed with supports because on the lip on the top of the bracket. You may need to scale the bracket from mm to inches otherwise it'll look tiny in your slicing program.
