Moon Phases Night Lamp

I had this moon phases lamp in my mind for a while, now that I'm getting into design for additive manufacturing I made the first try at it. I should improve it, but it is printable and working at this stage.

**Improved:**
V2 added, central column is now thicker and wider, so the new version is both stronger and have little more space for wires and resistances. Download all-stl-V2.zip

The moon landscape is printed on the internal side, so during the day, it looks like just a simple sphere. Inside the sphere, there is a shadow-casting hemisphere geared to the bottom wheel. I think the assembly is pretty obvious, let me know if you need help.

As light source, I used an old 5v phone charger to power 3 yellow 3mm LEDs in parallel with a 50ohm resistance, you can use a single 5mm bright one and any cheap USB charger (size the resistance accordingly).

I printed everything at 0.16mm resolution, of course, lower is better, especially for moon-top but expect a 24h+ print time.
