There is also a link to the very affordable and bright lights on Amazon linked from his build.
As you can see from my original test print, you might want to add add and extra layer (about .5 mm) to the back/height during slicing to eliminate the ultra bright and/or sparkly sections.
The author marked this model as their own original creation.
