Table Shadow Lantern – Folk Rosette

The tealight sits raised on a pedestal inside a 124 mm ring wall. The openings in the wall are not drawn by hand: each one is the exact central projection, from the flame, of an image laid out on the table, so the light lands on the table as a Polish folk paper-cut (wycinanka) rosette spread 15–45 cm around the lantern. It is mathematically computed projection geometry, verified with a ray-tracing simulation of the flame. Generated algorithmically (signed distance fields + marching cubes), checked watertight and printable.

Made for a standard IKEA tealight (Ø38 mm), which sits in a Ø39.6 mm socket; the top is open for heat. For a real flame print in PETG or ASA and never leave it unattended – an LED tealight is the safest choice, as PLA softens near heat.

BEST EFFECT

Use it on a flat, light-coloured table in a dark room. The tealight sits on the raised socket in the middle; the image depends on the flame height, so a standard IKEA tealight works best. Edges are softest far from the lantern because the flame is not a point source.
