Where it goes, and what color
This pair decides the material, so it comes first — everything after it is shape.
Specialty finish — priced at JOD/kg.
Shape
The form of the shade itself — its outline, its footprint, and how big it is.
Straight, flared, domed or bellied. Tapered and domed shapes need a different top and bottom width, so picking one sets those for you — adjust them below.
Each dot sets the shade’s width at that height. Drag left/right to shape necks, bellies, and flares. The top dot is the socket end.
Drag each dot toward or away from the center to shape the outline. The socket bore stays round.
What closes the top of the shade and carries the socket. Cutting material out of it trims weight and filament, and lets some light up the wall — a solid disc throws none.
Texture
The surface pattern printed into the wall. It changes how the shade catches light — and how it glows when lit.
Twist rotates the texture as it rises. Past a point the wall cannot follow it — the printability check will say so before you export.
Inner diffuser
Optional. A second printed shell inside the shade that hides the bulb and evens out the glow. It exports as its own STL.
A second printed shell that slips over the light socket inside your shade — hides the bare bulb and spreads the glow evenly. Auto-sized to your design.
Closed hides the bulb completely. Open lets light fall straight down — brighter on the table below.
Fittings
The socket it fits and the hardware it hangs from.
The hole cut through the cap. Measure the threaded collar of your socket or the fitter you are mounting to. Above 34 mm the shade is checked against a full-size A19 bulb, below that against a candelabra.
The socket bore is cut into the cap, so this changes the model. E26 is the standard size and E12 the candelabra; pick Custom to enter a diameter of your own.
Finish
How finely it prints — the layer height, and what that does to the surface.
Standard — 0.6 mm layers, cleanly printed. The fastest run, and the finish most shades are printed in.
Premium — 0.4 mm layers. Finer lines, a smoother surface, and a more even glow when the lamp is on. It spends longer on the machine, so the estimate reflects real print time rather than a flat surcharge.
Export
Binary STL, millimetres, Z-up, bottom of the shade on the build plate — the same millimetres shown throughout this app, so nothing is converted on the way out. The wall is a single closed surface, so slice it in vase / spiralise mode: no perimeters, no infill.
