C920 LED light ring for 86mm LED ring

First, this is not my design. I downloaded the F360 file for a C920 ring from Thingiverse and edited some of the parameters to make it fit an 86mm OD LED ring I bought on Amazon. I ordered this (https://smile.amazon.com/dp/B07QNL8T8R), expecting a 65mm ring, but the one I was send was 86mm. I looked around and found a ring with a Fusion 360 design file that had parameters for ring OD and width. I tweaked the settings to make it work with 86mm, but when I was done I could not find the Thingiverse entry for the design I downloaded. All the ones I found looking this time around did not have parameterized variables for dimensions. If you're the author and/or you know which thing I got the design from, please let me know and I'll attribute it correctly.

Anyway, here's a C920 adapter for an 86mm LED ring.
