I made this base to install 3 SMD leds inside of it, the idea was if I need to take a closer look I dont get blind with the light and be able to see the details I need it. Also I want it a bit away from the heat.
This was made thinking in install SMD leds and that is what it have inside at the moment in my printer but may work with normal ones.
Power can be obtain from the main fan that is the one its always working.
Worked for me, I hope it works for you.
Sorry for my bad english.
Updated, design cleaned and reinforced.
Infill can be even 15 but I like me stuff to be strong.
Some leds are really hot, use ABS if you have that kind of leds, PLA may work to with a good infill.
Mines are hot the infill is 45%.
Supports are necessary.
