About this 3D model

These disks can be used to determine what figures hit hit by area-of-effect weapons. This is based on the Warhammer system, which uses 3", 5", and a cone with the dimensions of 2.5" x 8". I made lazzzorable patterns to cut your own, with a 0.25" hole in the center to put a handle--I just used a 1/4"x2" bolt.
