Here is a cheap workaround if you don’t have access to a 3D printer. Via Hackster.io:
For most people, designing and fabricating a case to house an electronics project is the one of the hardest parts of the entire process. CAD and mechanical design are skills that take years to develop—even after going to college specifically for that, I was still only mediocre at it when I started my career. If you’re still learning CAD, a great way to keep your projects going is to prototype your enclosures first.
The process is simple enough for anyone to follow along with: just trace the screen and cut it out. Josh uses hot glue to layer the cardboard, and to attached the components to the back of the display. This is a fantastic way to quickly build a functional prototype, and gives you something to reference if you decide to actually create a CAD model for 3D printing or CNC machining.
