With this you can mount a 14x8mm LED bar above your Ender 3 V3 KE or SE. Slide the LED bar in from the side and then clip it onto the topbar of your printer. I made a dual bar version so you don't have to!
I printed this from PETG, 100% walls.
The author remixed this model.
I used the clip on part and made it thicker. Flipped the holder part upside down and made it to fit the 14x8mm LED bars.
