FFXIV Metal Work Lantern: A 3D printable lamp from Final Fantasy XIV, for LED and battery power, can use PET from 2 litre bottle for glass.

I took the Metal Work Lantern 3d model from Final Fantasy XIV and made it higher quality, and printable. The lantern in the game is an absurdly large size, however I think 25CM tall would be a great sized lantern IRL. You will need to modify it to fit your choice of illumination. There should be enough space in the base to hold a lithium battery. The top has mesh errors but Cura handles them fine. I have included the original raw .OBJ so you can compare. -Rinoa
