3D Scan Model Preparation for Printing

I need help editing a 3D model so it can be 3D printed. The model was created from a drone scan. The model is already available in multiple 3D file formats, but some parts of the geometry did not scan correctly and need to be repaired. Please note: This job is open to U.S. based freelancers only. Scope of Work: Please use professional 3D modeling software to: 1. Fix missing geometry - Repair areas where the scan did not capture the full structure. - One vertical support column is missing a chunk and needs to be rebuilt cleanly. - The bottom side of the structure also needs to be repaired where the scan is incomplete. 2. Clean up the model for 3D printing - Make the model watertight and printable. - Remove scan errors, broken surfaces, holes, and bad mesh areas. - Make sure the geometry is suitable for 3D printing. 3. Fix clipped faces and textures -Some side faces were clipped during the scan. - These faces should be cleaned up and recolored. - A plain grey color is acceptable for repaired or clipped areas. 4. Scale the model - The final model must fit within the print volume of a Bambu Lab H2C printer. - Maximum size: 330 mm x 320 mm x 320 mm - Please scale the model so it fits within this volume. 5. Export the final file - Final deliverable must be in 3MF format - The file must be ready to open and print in Bambu Studio or similar slicing software. Deliverables: - Final repaired 3D model in 3MF format -Model scaled to fit within 330 mm x 320 mm x 320 mm - Clean, printable geometry - Repaired missing support and underside areas - Grey recolored surfaces where needed Confidentiality Requirements: This project contains confidential and proprietary information. The selected freelancer must be located in the United States, must be willing to sign a non-disclosure agreement, and must not copy, share, publish, distribute, display, reuse, or disclose any project files, images, models, screenshots, results, or related materials to any third party or in any portfolio, website, social media post, marketing material, case study, or public work sample. Important Requirements: - Experience repairing drone scan, LiDAR, or photogrammetry models is preferred. - Experience preparing files for 3D printing is required. - Please mention what software you will use - Please confirm that you can deliver a 3MF file ready for 3D printing. To Apply: Please send examples of similar 3D model repair or 3D printing preparation work. In your response, please include: - Your anticipated turnaround time - Your proposed total cost
