@gamingonlinux Yeah €55 for a piece of plastic doesn't sound bad at all, right? For that price it should have been from different materials, I'd say.
If you want it plastic, just print it on a 3D printer, treat it in food-grade epoxy and you're good-to-go. If you don't plan on using it for food, you can skip the epoxy.
