Sanwu laser beam expander support ring and cover

thingiverse

I required assistance to ensure the Sanwu beam expander was properly secured, as it tends to come loose on the 9mm threaded barrel if not held firmly in place. Additionally, I sought a protective covering for the optics to shield them from potential damage. To achieve these goals, I swiftly created a design using Sketchup and promptly printed out the necessary parts. The components were produced with luminescent material, allowing the ring and cover to be easily visible even in dark environments.
