A Halloween pumpkin you print flat: two honeycomb nets that you warm and press into halves, then close round a battery LED tea light. It is 104 mm wide and about 60 mm deep, and the light shines out through every cell. Hang it from the hole in its stem or set it in a bowl.
Made with our mesh former. Each net prints in about 80 minutes, with no supports. The press is printed once and makes both halves, because the pumpkin is symmetric. The creases between the lobes come from the press itself, so every half comes out with the same ribs.
Print it in orange PETG for the classic look, or in a glow-in-the-dark filament. The zip has both nets, the plug, the cavity, a print sheet and the outline as an SVG for the mesh former.
Shown as a 3D render of the closed pumpkin in front of the two press halves, not a photo.
What you need
- About 18 g of orange PETG or PLA per pumpkin, and 95 g of PLA once for the press
- A battery LED tea light (never a real candle)
- A heat gun, or a hair dryer on its hottest setting
How to make it
- Print the front net, the back net, the plug and the cavity, all flat on the bed.
- Lay the front net in the cavity's pocket, flat face down, so the small pins go through the holes in its rim.
- Warm it with the heat gun kept moving 15 to 20 cm away until it goes limp, push the plug straight down and hold it for a minute while it cools.
- Do the same with the back net in the same press.
- Switch on an LED tea light, set it in one half and press the other half on by its pins.
