This box needs some care and attention to print perfectly because it's very wide and not very tall. If you're not careful, the corners will peel upwards and warp the shape of the box. Since the electronics aren't at all packed in, this probably won't matter too much if it happens. Also, get ready for some long prints - even the lid took about two and a half hours on my Ultimaker.For details about the electronics to go inside, take a look at http://electronicsfordogs.com/articles/control-amplifier-squeezeboxDepeding how you make the electronics, you may need to move some of the holes around. I've included the Sketchup source file so you can do this.
