This is a lampshade for the ANSMANN NL-2B socket LED-nightlight. It reduces the brightness in the set direction, but since the back remains bright, it still remains quite bright in the room. I have increased the shading effect by gluing in a semi-transparent handicraft foil from the inside.
As you can see on the photos, it is recommended to print the thing in an upright position. The horizontal position chosen by me leads to an uneven surface due to the round shape. In my defense, however, I would like to say that it was one of my first 3-D prints ever ... ;-)
