Thanks guys, but it's not very usable (the cast is the yellow one). One of the 'ears' is caved in, I had a registration key there and I think as it's fallen out of the mother mold it's pulled that area of the mold down with it. There's also some dimpling around the keys that are on the visor. In short I've molded it too thin. I'm re-molding as we speak. I'm confident I can fix these issues though. In parts the mold is about 2mm, I had no idea it was that thin, working in patches because of the reduced pot life of the silicone I was using didn't help. I thought about pulling the old mold back over the master and adding some thickness but now that it's already been removed I'm concerned about warping any of the shapes. Luckily I've traded it in for some Elastosil ow and it's been beautiful to work with. With any luck I'll be casting EVA 2.0 within the week.
