I was interested in ‘mushroom lamps’, and what seemed complicated to me was creating a satisfactory lampshade/arm assembly without a support. The trick? A ring-shaped component that slots into the base of the arms to secure the socket.

In terms of appearance, I therefore went with a mushroom lamp and reworked the mesh of the outer surface, creating triangular reinforcements of varying sizes depending on the lamp’s height (dense at the base, less dense in the middle, and dense again at the top).

For those who are interested, here’s the workflow:

AutoCAD: modelling the lamp shape + technical parts

Blender: rendering the outer surfaces

→ “Weight paint” (Tissue formula) across the height of the lamp: dual radial mode

→ Decimate on the overall mesh based on the weight paint

→ Crease, Extrude and Scale on triangular faces

→ Crease of 0.9 on the original triangular edges and a crease of 0.2 on the edges resulting from the scale

→ Surface subdivision on the overall surface  


**The STL model has the following dimensions: 25 cm in diameter (external) x 30.4 cm H**
