This is the amazing moon lamp by Frank Deschner, with the STL bug fixed. 

It prints flawlessy as the original, but you don't have to worry about the nasty layer messing up with your printer and fan, in case you slice it with anything other than prusa slicer (e.g. Cura, s3d etc.).

All I did was to import it with meshmixer and fixed it with the default repair settings, and export it (now it takes about 250mb, I didn't dare to reduce it)

I tested it with  s3d, 0.15 layer height, 2 outline perimeter, 7 top  layers, 5 bottom layers, printed in white PLA on a mk2s (Caribou 420 mod)
