Making a blueprint doesn't take much, all you gotta do is decide the measurements and draw straight lines. I can't draw anything more than a stick figureThese are my blueprints, all measurements are in mm. If you're making it yourself i suggest you use a butt joint as the miter joint is very hard to get 90° if you don't have the right tools. You can decide how much of a curve, if any, you want on the top yourself. The blueprints are drawn with supports for the control panel since that was my original design. The guy who made the box for me said he could cut a groove instead, so i went with that.This is a good site with different layouts for the buttons and joystick, print them out and see how they feel.
