I am in desperate need of the largest circular disk (with a small hole in the center) from a Czech sci-fi kit company called "Andromeda." This company made the "Bione," "Sirrah," "Raoul," etc.

The disk has grooves all around the edges---kind of looks like a UFO flying saucer.

Thanks.

I've got it in a couple of my kits (Sirrah, Kaitos), but it appears to be fairly major piece and wouldn't be able to part with it. Can you cast one out of resin?

I never did the resin approach and the cost to buy the resin and make the molds would surely be more than finding and buying another kit for that very part.
