Custom designed Empire Strikes Back style lightsaber model I made on Autodesk Inventor for printing with a DLP printer system. Model contains high-detail, including a crystal assembly within the control hilt portion. Separate components were designed to be press-fit for easy assembly without additional fasteners. These 4 components are available as STLs here, but have yet to be optimized for slicing, support, and exposure times. Please feel free to contact with any questions regarding this item.e
