I designed a lamp for my espresso bar and 3D printed it in one piece
The designer lamps in my house

A personal tour of a designer lamp collection, from the Artemide Tolomeo and Richard Sapper's Tizio to Isamu Noguchi's Akari series. The author explains the history and design details of each piece, admits they aren't cheap, and shares how he 3D-printed custom adapters for some—including his own Block Lamp design.
I love lamps so much that I designed one myself.
