Animatronic Skull Chassis Design

I want someone to design a 3d Animatronic head (roughly 12 × 15 cm) - a 3D-printable internal framework that can be assembled straight from the printer and driven by standard hobby servos. Outer skin, eyes, or teeth not required.

Core mechanics
• Jaw: must hinge downward about 10 mm with smooth, repeatable motion and room to mount a micro/mini servo for actuation.
• Neck base: should let the head pan ±60 ° left/right, again powered by a hobby servo or compact geared motor.
• Exact dimensions will be supplied when we start the project.

File requirements
I work in Fusion 360, so please send the native .f3d file alongside export-ready STL and/or STEP. A short motion simulation or screencast demonstrating both the jaw drop and neck rotation before final hand-off will let me verify everything before printing.

Timeline: 2 to 3 days.

Deliverables
1. Fusion 360 design file (.f3d)
2. Print-ready STLs/STEPs of all parts
3. A brief motion simulation video or embedded study showing the jaw and neck movements

If you’ve built compact animatronic mechanisms before and can hit this deadline, let’s get started.
