This is the design I have decided on for the doors to the turret.
The oatmeal boxes (2) are going to be the turret base. The white paper in the middle of the picture are the door patterns. The blue tape is around slats of boards for the doors. I am going to glue the boards together and glue detail on the doors. Then I am going to pour resin doors. I then am going to use a blow dryer on the resin doors and bend them slightly to fit the curve of the oatmeal box.
