Tomm's 3 Axis Talking Skull

My Take on a 3D Printed Talking Skull with Advanced Features (Work in Progress) https://youtu.be/N_Aj8f7IDIM https://youtu.be/ZblO7FgPndc This project is fully 3D printed, requiring only 90 grams of cheap servo motors, heavy wire stock, and small screws. The wire used for the control arms comes from marking flags at the dollar store, which are perfect for RC control arms and similar applications. To connect the servo ball joint, I glued six pieces of wire in place, cutting them to size as needed. For the jaw servo, no ball joint is required. I also used the wire to create a 90-degree bend on the top center post, holding the control arms for tilt and nod movements. However, I didn't glue it in place until all calibration was complete. To trim the center post to fit, I used the excess material to make washers that I rounded with sandpaper to shim between the tilt and nod control arms on the center post. The screws used to attach the control arm to the servo arm came from a 1806 Quad Motor mount. Although I haven't measured their size yet, I can look it up later and update this information accordingly. For the top servo connection cap, I applied pressure to fit it perfectly, planning to glue it in place once I'm satisfied with its alignment. The jaw servo will be placed on the side of the skull and secured using hot glue. A custom-cut slot will be created for the control arm and push rod, aligning with the jaw motion point. To complete this project, I'll also glue a bearing to the rod end and mount it securely to the plate, ensuring that the center hole is centered on the plate's corresponding hole. Update (03 Oct 2019): I've uploaded the coding for Arduino to control the Servo's via Xlights or Vixen3. After testing, I found that it works as expected. However, the code may contain some unnecessary parts; if you can clean it up and send me your final results, I'd greatly appreciate it. This update allows you to control up to six servo motors on a single D1-mini using E1.31 wifi connectivity.
