This may seem like a bit of a weird question, but I'm working on some 3D printed Battletech minis for my son for Christmas. I was thinking I might try and make fake packaging and I'm curious if anyone has tried doing that before?
The box is easy enough as is the clear plastic front, but the clamshell plastic support has me stumped. I could just carve it out of foam, but that is opaque.
Essentially I'm trying to think of a way to spoof something like this and am looking for suggestions for supporting material.:

It will be 5 3d printed mechs in Ghost Bear colors with a tin of Ghost Bear dice (which may or may not go in the box)
