Simple, elegant lampshade project takes full advantage of the layering process of additive manufacturing. Print in CPE or PLA translucent colors (for a LED or compact fluorescent bulb, don’t use a hot bulb!), and experiment with nozzle widths to change behavior of diffusion and hardiness of the lampshade.
The designer Rudy Hermus included the Blender design file should you want to tweak or repeat this project with another 2D base polygon.
“A twisted square design lampshade for a lamp socket of up to 30 mm.”
