This is a ring light for the Anycubic Kobra.
I purchased the Led Strip from Wish.com

I cut the led strip to the length that I needed, then ran the cable to a plug
I used clear UV resin to attach the strip to the plastic ring back, then
I used double stick tape to attach the ring back to the Hotend cover.

***I didn't like that it covered the front view of the nozzle, so I cut it and modified it after printing.
I'm still not completely pleased with having the cord on the front, so I may come up with another version later.

*The Fusion model is pretty accurate, and I would suggest using it as a template to create other attachments of your own.
Fusion 360 is available for free to Hobbyists. I would recommend getting it.
