This is the Essential Oil Diffuser Egg. Assemble the parts, add water and a couple of drops of your essential oils, and insert the diffuser unit. This will create a cold mist that carries the scent over the edge of the egg while the colored lights play against the bottom of the mist. I have included an STL file under the Download STL/CAD Files section to go along with the 3MF file. I have also included a free commercial license for those who wish to sell their prints (NOT the files). This is the diffuser unit I use.
NOTE: I HIGHLY recommend either sealing the water holder or using a plastic bag to prevent eventual water leakage.
