This is a simple lamp, easy to print.

It was made for the kind of socket shown in the image (E14). The distance between the screw orifices is 28mm (1.1 in). I used a small led lamp.

Use translucent filament. You can use white, but the lighting will be dim.
It's faster to print with more perimeters than more infill. You can use an infill of 20 to 30%, to give the base more weight. The lamp body was printed with 4 shells

You will need a piece of wire with the length you want. Fit a middle wire switch and a plug and then insert the cord through the base orifice (6mm). Before connecting it to the socket, make a knot at the beginning to avoid pulling it and losing electrical contact. There is an indentation on the lamp to allow it to be fitted to the base.

Use two 3x20mm screws to fix the socket.

Hope you like it.

Edit: added a second version, with flat walls.
