This lamp shade covers your light bulb.
It fits for standard E27 (40mm.) sockets.
The sample was printed, using few years old PLA. I was amazed that little stringing was the only minor flaw, which was corrected by using the heat-gun(hair dryer should work also).

My LED bulb does not emit enough heat to melt the PLA. But if you use incandescent light bulb, you should consider other materials.
On the profile brim is added for “extra safety”.

If you like it, don't be afraid to show it ;)
