This is designed to replace a broken Sony 49mm lens cap but may be able fit other lens with the same diameter, as long as the lens curvature is fairly flat.

This can be printed as one piece with a fair amount of bridging, or as two pieces and carefully assembled together. I've done both without issues.

Good printing!
