Topic: Polystyrene insert for NES console box?

Is there anywhere I can get a polystyrene shell for my NES box? It's complete just no polystyrene to hold the console or controllers while in the box, and don't want the box to get flattened without it, any help would be great, thanks

that's a very specific request.
have you tried eBay, or other online avenues for second hand items?
if not, there's always 3D printing probably?

Have you tried making one with a polystyrene cutter and glue?
