https://youtu.be/ZxrJb0E9sgw https://youtu.be/UD-hKFLpOKw I designed and 3D printed "Darth 3.0: A 3D Printed Animated Darth Vader Helmet" for our grandkids who are Star Wars fans! This 3.0 version incorporates an ESP32, stepper motor drivers and stepper motors to provide a more complicated and programmable animation sequence. As in my previous Darth animated helmet design, the only contact between each slice must be the pins in the slots, thus careful 3D printing (no warping) and assembly (bearings completely flush with the top and bottom of each slice) are required to successfully 3D print and assemble this model. As usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to comment as I do make plenty of mistakes. Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.8.0, and 3D printed in PLA on Ultimaker S5s.
