This is an essential oil aroma diffuser egg. Assemble the parts, add water and a few drops of essential oil, then insert the aroma device. This will produce a cold mist, bringing the fragrance to the edge of the egg, while colorful lights flicker at the bottom of the mist. I have included an STL file in the "Download STL/CAD files" section to match the 3MF file. I have also provided a free commercial license for those who wish to sell their printed productsThisIt's the aromatherapy device I'm using.
Note: I strongly recommend sealing water containers or using plastic bags to prevent eventual water leakage.
