Turner states that owls have no natural predators, so the Court of Owls won't know what it's like to be hunted. Ignoring that the name of an organization doesn't mean its members behave exactly like the animal its named for, owls do in fact have natural predators. Wildcats, wild canines, bears, other birds of prey, and even snakes, squirrels, weasels, raccoons, and skunks eat owls.
It is not possible to create a mask of the type (finish/detail level/heft/durability) shown using a 3D printer.
The Gotham Knights are able to determine the location and time the Court of Owls will meet because they have possession of at least 4 watches owned by members of the Court. It might appear as if they needed multiple watches to find this meeting, meaning no single member could know the details on their own. However, the only advantage to having multiple watches is demonstrating they all acted the same, showing it was significant and not random damage, as they first thought.
In actuality, all the watches gave all the information. They all spun and stopped at certain specific times, giving first the meeting's time (9pm) then pieces of the latitude and longitude (7:21:02 and 3:05:13) with each stop. All the time stops together gave the time and place of the meeting.

After Duela secrets the map under her slinky evening dress, there is very clearly no 18 inch long, 2 inch wide piece of rolled metal under the dress.
When Harvey enters the safe house to find Cressida missing, he becomes enraged after not seeing her in the main room and finding the window sealed shut. There is a door against the side wall. While it is unknown what that leads to (another room, a closet, a bathroom), Harvey should have checked there before assuming Cressida was gone from the apartment.
