This is a close representation of the lightsaber used by Anakin Skywalker in Star Wars Episode III: Revenge of the Sith. I tried my best using pictures and my own hasbro replica lightsaber in order to create this model. The material seen on the model comes directly from 3dsmax 2021 default material and I used the Arnold Render in order to create the preview photos.
** I added a .stl format for 3d printing, please let me know if it works well.
