This is simply a rework of EunchanPark's light ring project for the Logitech c920. I took his mesh into Fusion360 and reverse engineered a totally new model.

The changes I made th the original are:

Changed the thickness of the model in front of the LEDs. The filament I used was a PETG white that had a lot of translucence. I wanted more difusion.

I added side protrusions that keep the light centered side to side on the webcam.

I made several changes to the look of the part.

The light ring I used was this one available on Amazon, I believe it is identical to the one used in the original version.
