I wanted a nice way to display my lightsabers I bought with my family while visiting Disney. Designed it so the lightsabers are arranged to have their buttons facing outward to turn them on easily. Left holder is for the longer of the lightsabers (they may look similar but have different widths). No supports Necessary.
To hang on the wall I would find a stud and mounting the cleat and sliding the mount on over it. No supports should be necessary.
