I created this Lego Wall Lamp with unmodified files from https://printabrick.org
Thanks for the people who made the bricks available for printing.
The bricks where printed at 300% scale.

To mount the lamp on the wall I designed a simple insert.
The insert is already the right size, so print that one at 100%.

For the wire I drilled a hole in the side of the large brick. The 0.75mm2 inner wires will just fit between the bottom pins and the side of the brick as you can see in the picture.
I used and old shoelace for the part of the wires from the lego to the lamp socket.

Please post your make if you decide to make one. I appreciate that.
