We are looking for an experienced 3D artist to modify an existing animal STL into a print-in-place articulated model with controlled flexibility, optimized for PLA printing. The objective is to achieve smooth mechanical flexibility using segmentation and joint design, while preserving the original form and maintaining structural strength and printability. Scope of Work Convert provided STL into a segmented, articulated structure Maintain original proportions and silhouette Ensure print-in-place functionality (no assembly required) Introduce controlled flexibility in key areas while keeping overall structure stable Articulation Guidelines (Critical) Use a spine-based segmentation approach as the primary articulation system Apply higher flexibility in: Neck Tail Apply moderate flexibility in: Main body Keep fins/limbs minimally articulated or structurally rigid to avoid breakage Use interlocking or ball-joint style connections suitable for PLA Maintain a clean outer silhouette (avoid overly mechanical or toy-like segmentation) Avoid excessive segmentation that: Weakens structure Increases print time unnecessarily Technical Requirements Optimized for PLA printing (rigid material constraints) Joint tolerances: ~0.3–0.5 mm clearance Smooth articulation without fusion or breakage Clean, manifold geometry (print-ready) Balanced segmentation (not overly dense) Additional Requirement Apply a 2-tone design setup: Clear upper/lower body separation Should support: Dual-color printing OR Easy painting (Use either material IDs or mesh separation as appropriate) Deliverables Final print-ready STL (single-piece articulated model) Optional: separated STL for dual-color printing Clean geometry with no errors (non-manifold, flipped normals, etc.) ⏱️ Timeline 2–3 days for first working version 1 revision round included Notes Reference examples of segmented/flexi-style models will be provided via chat This is a controlled articulation task, not a generic flexi toy design Focus is on balance between flexibility, strength, and aesthetics

With my extensive experience in 3D printing and designing, I am confident I can deliver outstanding results for your articulated animal STL project. My portfolio demonstrates my ability to create accurate and printable 3D models while preserving the form and structural strength of the object, which is exactly what you're looking for. One key aspect of this project is achieving controlled flexibility without sacrificing the overall structure. I am well-versed with spine-based segmentation and ball-joint style connections, enabling me to provide optimal flexibility in the specific areas you need, such as the neck and tail, while keeping the main body stable. Moreover, I understand the importance of creating a clean outer silhouette that doesn't compromise the appearance or printability. In terms of technical requirements, I'm familiar with PLA material constraints and can design according to your joint tolerances. I prioritize clean geometry, manifold design and a balanced level of segmentation to simplify and optimize the printing process. Additionally, my skills in dual-color printing or identifying mesh separation will allow me to deliver on your 2-tone design request. Rest assured that my approach will not only meet but exceed your expectations for this project. Let's bring your imaginative creation to life!
