Carved Jack-o'-Lantern for LED Tea Light – Realistic Halloween Pumpkin, No Supports, 2 Faces

What it is

A jack-o'-lantern that looks like a real carved pumpkin: eleven rounded ribs of slightly different widths, deep creases that gather around the stem, and a lid cut with a zigzag knife line. Drop a standard LED tea light in, put the lid back and the face glows. Two faces to choose from, classic and spooky, with the same lid.

Features

• Smooth, organic body with 11 uneven ribs and fine streaks, 108 × 105 × 68 mm (about 93 mm tall with the lid)

• Lid cut like the real thing: a zigzag edge with one taller tooth at the back, so it only goes on one way and cannot turn

• The lid sits on a 46° cone that centres it; no collar, no clips

• Curved, fluted stem with a flared base

• Thick wall under the lid, like real pumpkin flesh, so the face edges catch the light

• Fits any Ø 38 × 16 mm LED tea light, centred by a ring in the floor; a Ø 16 mm hole underneath lets you push it out or reach its switch

• Every face opening has pointed or toothed tops (45° or steeper): nothing to bridge, nothing to support

Print settings

• PLA, 0.4 mm nozzle, 0.2 mm layers

• No supports, no brim. Body upright, lid flat side down (as in the 3MF)

• 3 perimeters, 15 % infill

• About 3 h 30 for the body and 1 h 15 for the lid, around 85 g + 27 g (estimates, not sliced on every printer)

• Thin orange PLA glows nicely when the light is on

• LED tea lights only, never a real candle

Colours

• Orange for body and lid (slot 1 in the 3MF; I load orange in place of my red)

• Green stem (slot 4): the colour only changes in the top of the lid

• Single colour: citrouille-classique-orange.stl or citrouille-effrayant-orange.stl and couvercle-une-couleur.stl

• File names are in French: citrouille = pumpkin, classique = classic, effrayant = spooky, couvercle = lid

Make it yours

The whole model comes from one Python script, gen.py (manifold3d): number of ribs, rib depth and irregularity, profile, wall thickness, lid cut and teeth, stem, tea light size, face shapes. The script checks every overhang, every top edge of the face cut-outs, that the tea light goes through the opening and sits in its ring, and that the lid seats.

Designed with AI assistance (parametric Python script).
