Reply to Custom X1 Case

so Ive been using the box that the x1 comes in as a sort of case to elevate the x1 to mixer height...
anyways today I was believeing about a way to make a case where I can put a soundcard inside. I believe I came up with a pretty cool idea, but I would like to make it out of something other than cardboard, any tips or ideas out there?

the bottom piece would act as some sort of lid.
