This is a lampshade (20cm / 7.9 inch diameter) with the actual (if exaggerated) topography of the moon. I printed it with blue glow-in-the-dark material so it shines even when the lights are off. The differences to the original moon lamp by 'moononournation' are:

• larger 20 cm diameter
• the inner surface is spherical, the outer suface has the moon topography, this means the wall-thickness will vary with topography and thus will be more visible than in the original moon-lamp
• you can print it in one go without skirt or support material
• the cone in the bottom is the print-support and should be cut off after printing
• there is a hole which is just big enough for ordinary lightbulbs below the cone so you can turn the lampshade upside-down after printing, push the lightbulb through the hole and attach it to the lamp-cable with a wire.
