Here is my "The Wall" Lamp!
Print it upside down, don't use support! Use bridging instead.
Tape a piece of paper around. I used DIN A4 and cut a 82 x 295mm piece off.
PLEASE DON'T BE STUPID - USE A LED BULB!
Every other bulb gets way too hot.
I sticked the E27 bulb with double sided tape to the ring of the lampshade.
You can use any E27 Socket you want. I used a simple socket from the hardware store in combination with my wall mount.
