Inspired by a shattered light bulb, this design can be used to fit over an existing light fixture - in my case I wanted to save an old Ikea lamp that worked perfectly well, but the lampshade was old and ugly. Often old products like this are too easy to just throw away, when with a bit of 3D printing it can be re-invented and given a new lease on life.
The smallest inside diameter is 31mm so just make sure you can slide this over your intended light fixture - if not just scale the print up to fit! This particular print was done on an Up! Plus 2, using 0.2mm layer thickness. Very little support material was needed.
