This is a gunsight for a 1/5th scale Mitsubishi A6M3 Zero fighter. Model scaled down from original size to 50%. Prints in about an hour and a half. The only piece of this print that didn't come out was the ring. I recommend cutting the ring off when you prepare it and laying it flat and printing it as a separate part. Supports took a little work to get off. Cut off the screens and replace them with a piece of glass just like the real thing.
