MoonLight

This nightlight or desk lamp is a model of our Moon's surface illuminated by a subterranean crown. Twisting the surface turns the light on and off.

The most visible topographic feature is the giant far-side South Pole–Aitken basin, some 2,240 km (1,390 mi) in diameter, the largest crater on the Moon and the largest known crater in the Solar System.

Supplies

• All parts printed, 0.15 layer height suggested
• 4 x Bright white 5mm LEDs (here)
• 1 x 9 Volt battery
• 1 x 200 Ohm resistor
• Wire or this Electric Paint as I used. Very useful for building circuits on printed objects.
• Krazy Glue or Gorilla Glue (the only two I trust)

Doesn't Matter

Doesn't Matter

0.15mm, print the Moon part as high as possible

Recommended > 20% infill

• Material: Glow-in-the-dark PLA (60 C heated bed, 210 C nozzle)
• No support needed, the Cap is optional for diffusing the light

Switch

• This light is built to turn on/off by twisting the Moon (lefty loosie, righty tighty. RIGHT = ON).
• The Collar and Base have structures which touch at the end of the twist. Use that to close/open the circuit between the LEDs and the battery.
• The Electric Paint listed in the description was extremely useful. I strongly recommend it for this build and many other 3D printed projects. It may add measurable resistance but in this case that saves battery life!

LED Assembly

1) Print LED Crown part. High infill, high resolution suggested.
2) Insert LEDs by aligning the flat edge of each bulb with the square-shaped whole on each face. This ensures all LEDs are wired correctly.
3) Combine all positive leads by twisting or soldering together. Repeat for negative leads. (See pictures for an example)
