It's a free swinging lamp on a broomstick. It can be installed on the side of a closet or on the wall. Because my room is too small I only created the mount to install it on a surface which is accessible from both sides.
If anyone wants a version to put the lamp on a wall just let me know and I will do my best to alter the mount.

Things you need:

• broomstick (d=25mm max.)
• bulb fitting
• electric cable (use some fancy color :-)
• nice, big lamp or a normal one with a lamp shade
• switch, power plug
• hook to screw into the wall or your closet
• M4 screw and nut
• 3d printed mount

Drill a hole (size of cable) into the top of the broomstick and another two holes at about 2/3 of the height at a distance of about 3cm. Connect the cable and the bulb fitting and direct the cable through the holes. Make a loop into the cable at whatever length you like. This loop is placed into the hook. Just try a couple of different length and distances of the mount and hook to find your perfect angle.
