Would making a mold by lining the interior space with foil, spray it with releasing agent so it won't stick to the original console. Then pour in liquid latex and while it's setting up; press in treated items like a a few small boxes i.e. square, rectangular etc... and remove them when it cures. This way you can design it the way you want and it'll be flexible for easier removal for cleaning. I'm just thinking outside the box...
