Lamp Shade Designer

What is Lamp Shade Designer?

Lamp Shade Designer is a free browser tool for perforated lamp shades. You shape the silhouette by dragging points on a profile drawing, or start from a family such as cone, drum, empire, bell, ogee, sphere, hourglass or pagoda, and the shade updates in a 3D view. A Lamp on view puts a bulb inside and casts the hole pattern onto a floor and wall, and an Overhang check view marks the parts that will be hard to print.

Below the silhouette are height, wall and girth, a cross-section (circle, polygon, squircle, lobed, star or scalloped), twist, flutes and waves, and a perforation pattern (grid, staggered, hex packed, spiral or scatter) with seven hole shapes, hole size, rows, columns and a size gradient. You can stack nested inner layers with their own color and opacity, pick the bulb (three E27 shapes, GU10 or LED filament) and the fitter (E27 shade ring, spider, threaded Uno, clip-on or pendant cord grip), and switch on vase mode. A status line gives the size, hole count, filament weight and which Bambu printers the shade fits.

Downloads are the shade as STL or 3MF and the fitter as STL or STEP; the readme says the 3MF keeps each layer as its own colored object for multi-material printing. There is no account, and designs can be saved in the browser, exported or shared as a link. The code is public on GitHub but has no license file, and nothing on the site covers selling prints. It suits makers who want a light-casting shade with a fitter for a standard lamp holder.
