I can certainly help you modify your STL file for your 3D printing project. Splitting a mask model while ensuring it remains functional and printable requires a precise approach, and I have extensive experience in mesh manipulation and Boolean operations specifically for 3D printing. I will start by resizing the model to your exact percentage requirements to ensure the fit is perfect. For the cut, I will perform a clean split and then design custom-fit pin slots and corresponding pins. This will allow for easy alignment and a strong mechanical bond during assembly. I will also handle the addition or removal of details as requested, ensuring the mesh remains manifold and error-free for your slicer. My workflow typically involves using tools like 3ds max to ensure that the wall thickness remains consistent and that the pins are designed with the necessary tolerances (usually 0.2mm to 0.3mm) so they fit snugly without needing excessive sanding. I understand the importance of orientation and support structures, so I will make sure the split is placed in a way that minimizes visible seams and simplifies the printing process. I have worked on numerous wearable props and masks, handling everything from initial scaling to final post-processing preparations. I would be happy to share examples of my previous 3D printing modifications and split-part assemblies.
