If you're anything like me, you own the greatest film camera ever made, the Minolta Alpha 9, but unfortunately, the one you got a great deal for on eBay didn't come with an eye cup, and it's next to impossible to find a genuine replacement, or something that fits. I printed base in PLA and top in TPU and glued them together, but if you wanted, you could just print it as one piece in PLA, but I like the softer TPU for the piece that actually touches your eye.
