Solar Geode City

This is a solar lighting source to sirofsky's beautiful Geode City. The example LED holder file/pictured is a little rough, but is functional only. The LED's are 5mm diameter with space for the wiring on the back and is just hot-glued in. The rope/string lights did not direct enough light outward, so I replaced them with the three LED's and the lighting works very well. You want to use fairly clear/translucent filament. The interior white/translucent city piece is printed with Solutech Glow in the Dark, but it really doesn't glow much. Previously tried a translucent PETG green, but it blocked too much light. So any fairly clear/white/translucent filament should work.
The links/samples are for reference only. You may find something better. Haven't used the referenced solar string lights, but are similar to what I use except they are 100 bulbs vs 50.
For resistor, just confirm the voltage coming out of the solar panel, mine was about 10, and plug values into the resistor formula. LE
