This is some snap-on clips I designed for cable management for the articulating arm sold by Eakins on AliExpress - https://www.aliexpress.com/item/32977134987.html
I used 3 of each for my setup, it has cable channels for the LED ring, camera power and HDMI output.
I have also attached the Fusion360 files in case you need to modify it.
