Moon lamp project

The final product is a of a :

I’ve 3d printed a moon lamp and installed it on an old lava lamp stand.

The process:

1. 3D Printing

3D model:


I used the following settings, as recommended by the model designer:

  • material: white Overture’s PLA
  • Printer: Sovol SV06, no mods
  • Temp: 220C/60C
  • Layer height: Normal, 0.2 mm
  • Infill: 100%
  • Speed: 100mm/s
  • No supports
  • Slicer: Sovol Cura 1. 5. 4

I’ve tried to slice with Sovol Cura 1. 7. 2, but it crashed when I tried to save .gcode. I also tried with Prusa Slicer (for the first time), but it printed spaghetti. I didn’t have printer profiles correctly set up and I didn’t want to bother tuning, so I reverted back to old proven Sovol’s Cura. Maybe I’ll use it next time when I will fine-tune my printer profile.

Nevertheless, the slicers calculated the following times:

  • Sovol Cura 1.5.4: 4 days 16 hrs
  • Sovol Cura 1.7.2: 2 days
  • Prusa Slicer: 3 days.

The model shows a lot of red spots (overhangs), but it prints ok. Probably because of the tiny curves that attach to each other. See the green paths of the nozzle:

It took 4 days and 274g of filament to print the moon.

Designing the adapter:

My lava lamp broke a few years ago, but I kept the base. I wanted to fit the light on the old lava lamp base so I modified the author’s bayonet adapter and added the bottom part (purple) in TinkerCAD.

I printed it but supports were unavoidable. I had to cut and sand them off. The I doesn’t look good, but the bayonet connector will be hidden in the lamp anyway.

2. Assembling

I removed the old E14 bulb socket and replaced it with the E27 one, because it’s easier to find bigger bulbs that are more powerful. I used one 7W LED bulb I had at hand.

It emits a nice warm – white light.

I tried to fit the moon on the bulb, but the hole was too tight.

So I increased the hole for 1-2mm with Olfa-knife. Now it fits nicely:

This is a picture by day. At night it glows just enough that I can read it by the lamp.

It is magical to have a detailed celestial object so close.

But should I automate it with ? Naaa….

Thanks to all the people, who made this possible: the author of this 3d model, the original author, astronomers, photographers etc.
