3D-Printed Halloween Pumpkin Uses a Scotch Yoke to Open Its Mouth
Reading lead
Maker shamix3d has shared a 3D-printable Halloween pumpkin lantern whose mouth opens when the user rotates both hands. Its Scotch yoke mechanism converts that rotary input into linear motion. The model is arranged across two print plates: one for the pumpkin components and another for a light diffuser and head lifter. The listing says it is compatible with a range of Bambu Lab printers, including P1-, X1-, A1- and H-series models, and estimates print time at 3.4–4.6 hours. An assembly guide is included, and the design can accommodate a tealight or LED light. The supplied material describes a downloadable maker design, not a commercial product launch or independently tested performance.
