Parametric 3D lantern designer
Your lantern. Your scale.
Design it in your browser, watch it take shape live in 3D, export it as an STL file and print it yourself.
A lantern, built rib by rib.
Lumenrib is a parametric lantern designer that runs in your browser. You assemble a lantern from individual slender ribs that curve outwards, and you decide how tall it is, how wide it bulges and how many ribs it has.
When you are happy with the shape, you download it as an STL file and print it on an FDM 3D printer such as the Bambu Lab A1. No account, no cloud — just the tool and your printer.

Motifs
Decoration that grows out of the ribs.
Motifs sit directly on the ribs as raised relief. You choose how many there are, how large they are, how high up the lantern they sit and how deep the relief is.
Add a second or third row of motifs and the lantern throws a richer pattern of light and shadow once a candle or LED is inside.
Twist
A gentle turn changes everything.
Twist the ribs around the vertical axis and a straight, calm lantern becomes a flowing one. The twist angle runs from −90° to +90°, so you can turn it either way.
Combined with the curve tension of the bulge, the same ribs give you very different silhouettes.
Six starting points
Timeless
Classic
48 straight ribs, 160 mm tall, 200 mm belly diameter, no twist. The balanced base form to explore every direction from.
Seasonal
Christmas
168 mm tall with motif relief in two rows on the ribs. They throw a festive pattern of shadows when lit.
Wide
Lounge
150 mm tall, 230 mm belly diameter, 56 ribs. Stronger curve tension makes it the broadest of the six forms.
Dynamic
Helix Twist
175 mm tall, 44 ribs, twisted 45°. The ribs wind spirally from base to top ring.
Slender
Tall
230 mm tall at 190 mm belly diameter. The belly sits lower, giving a stretched silhouette.
Every preset is only a starting point. Once you have picked one, every parameter stays freely adjustable.

Motifs
Decoration on the ribs: number, size, height, relief depth and rows of motifs.
Candle compartment
Candle diameter and height, clearance to the wall and the recess in the base.
Stabilisers
Number, width and thickness of the stabilisers, plus the shape of their neck.
Night mode & colour
Preview your lantern with light and cast shadows, and choose its colour.
STL export
Download the finished lantern as an STL file for any slicer.
Built around a real light
Lumenrib is a tool, not a shop. It does one thing: it helps you shape a lantern that you can print at home.
Everything you see in the preview is what ends up in the STL file, so you can judge proportions, ribs and motifs before you print anything.
Hold the mouse button and drag to turn the lantern. Scroll to zoom in and out.
Switch on night mode to see the lantern glow and cast shadows, then switch it off again to check the shape in daylight.
Choose a colour for the preview, and adjust any value until the lantern looks the way you want it to.
The lantern is built around a real candle or LED light. Candle diameter and height are adjustable, so the compartment fits what you have.
