This is a Sphere Lamp based on my Mushroom Lamp Components Kit for 3D Printing https://www.amazon.com/dp/B0D9JS2BCT?maas=maas_adg_68D2673585D82EC787A193193460D8B2_afap_abs&ref_=aa_maas&tag=maas

The bottom can emit radiated shadow, and the top shell can emit diffuse lights.

I recommend using black filaments to print the top and bottom shells, if you want a white one, please change the middle part to another one(as the image below shows) , because the white filaments can not cover the light, you can see the inside shadow clearly.
