Inspired by NightSky's cover but uses these simpler "Angel Eyes" LED rings.

Also has a a model for an x-axis mount which holds a buck converter to drop the 24 v from the printer power supply to the 12 v required by the LED ring. Link below for the buck converter:

X-axis mount was an edit of the STL so not the best model. But it should slice and print fine.

Print instructions

Print ring cover face down with supports for the interior of the ring only.

X-axis mount may need a brim depending on filament used to keep from warping.

*V. 2 revised to have a tighter fit on the detents.  Previous version was too loose a fit.
