Ender3 G4 Led mount

thingiverse

This is an easy fix to illuminate the print bed since prints cannot photosynthesize on their own. A mini G4 1.5W LED bulb would be sufficient to cast some light. No supports are required, simply print it with the side facing up and you're good to go; I used PLA at a layer height of 0.2 mm and a fill density of 20%. Next, drill a small hole (2-3 mm) in the printed part for the electric wires to exit. Snip the LED bulb legs a bit shorter, then solder the wires onto them. Finally, remove the two screws from the profile, slide the part into place, and reattach the screws; it will fit loosely at first, allowing you to adjust its position as needed.
