Halloween pumpkin lamp

Spooky Jack-o'-Lantern with Lid – LED Pumpkin Lamp A classic carved Halloween pumpkin with an angry face, made for 3D printing. It has two parts: a hollow body and a lid with a twisted stem. Put an LED tealight inside, close the lid and the light shines through the eyes, nose and jagged grin. Both parts print without supports. Features - Two parts: the body and the lid. A standard LED tealight (Ø 38 mm) goes in through the top opening.

- Self-centering lid: the joint is a 45° cone, so the lid drops into place and sits straight. The clearance is about 0.4 mm.

- No supports needed: - The inside of the body has no overhang steeper than 45°.

- All face openings have arched or short bridged top edges, and no tooth hangs in mid-air.

- The lid prints standing on its flat bottom.

- Thin 1.6 mm walls, which is exactly 4 lines with a 0.4 mm nozzle. This saves filament and lets more light through.

- Flat, stable base about 68 mm across.
