I really liked the lithophane moon but had to scale it down to 80% to fit my printer bed. I also used a different candelabra base so I modified the original design. 

You can print this model at 100% and then print the original moon at 80% and it will fit together. 

I found the base to be a little loose so I took a heat gun and warmed up the “tabs” and gently bent them slightly upward which made it tighter and hold the base well into the moon lamp.

I used LED bulbs and they do not get hot and I keep them on 24/7
