3D Print-Ready Articulated Xenomorph Robot Model — Servo Mounts & Electronics Cavity
Budget: $60 – $90 CAD
I'm looking for an experienced 3D modeler to design a print-ready, articulated Xenomorph (Alien franchise) quadruped robot model optimized for FDM printing (PLA) and servo motor integration.
TECHNICAL SPECIFICATIONS:
• Overall size: approximately 25–30 cm long
• Must be delivered as separate STL parts (not a single fused mesh)
• Fully editable source file required (Fusion 360 .f3d or Blender .blend)
REQUIRED BODY PARTS (separate STL files):
- Head (with mouth cavity for HC-SR04 ultrasonic sensor: 45×20mm opening)
- Neck
- Thorax/body (main chassis)
- 2x Front legs (upper + lower segment each)
- 2x Rear legs (upper + lower + foot segment each — digitigrade/reverse knee style)
- Tail (2–3 segments)
MECHANICAL REQUIREMENTS:
- Thorax must have an internal hollow cavity: minimum 80×50×40mm to house ESP32 board + PCA9685 servo driver + 7.4V LiPo battery
- Each articulation point must include a servo horn mount:
• MG996R servo mount (40×20mm body slot) for rear hips and knees
• MG90S servo mount (22×12mm body slot) for front legs and tail
- 4mm screw holes at each joint for servo horn attachment
- PIR sensor window on dorsal thorax surface (circular opening, 23mm diameter)
- Removable belly panel on thorax for electronics access (snap fit or 2 screws)
PRINT REQUIREMENTS:
- All parts must print without supports where possible
- Minimum wall thickness: 2.5mm
- Tolerances: 0.3mm clearance at all joints
- No part larger than 200×200mm (standard print bed)
STYLE REFERENCE:
- Inspired by the H.R. Giger Xenomorph (Alien franchise) — elongated skull, dorsal tubes/spines, digitigrade rear legs, long tail with blade tip
- Stylized/simplified is acceptable — does not need to be hyper-detailed, functional mechanics are priority
DELIVERABLES:
- All separate STL files optimized for FDM printing
- Source file (Fusion 360 .f3d preferred, or Blender .blend)
- Simple assembly diagram (image or PDF)
