This is a light diffuser designed to be attached to the Olight 2, 3, 4, and possibly other models.

It is 3D printed using PETG materia.

To achieve smoother surfaces, a relatively large amount of tree support structures were used during the printing process.
 

Initially, the diffuser may fit a bit snugly when attaching it to the flashlight, but this tightness will ease up after a short period of use as the materials settle.

Two thinsg about the design: the wall thickness increases towards the middle at the top to ensure more even illumination. I also added a small hole, where hot air can escape.

I hope you enjoy the design and find it useful!
