Hello! I am trying to create some products using the Pymol Software for 3D printing. I save/export the file as Vrml 2 (.wrl), but when I try to upload it to shapeways, I get the message "model failed during repair." However, there is no additional information as to why it failed. I am new to coding, but when I download the file and compare the code to other models that have worked, I don't see obvious red flags. Any idea as to why my upload is failing? (I am attaching the zip file here). thank you!
