is it allowed to upload humain's sex parts ??
Although we do not want to screen all files uploaded to GrabCAD, it is our goal to create a community of professional mechanical engineers. Uploading models of human sex parts is not in line with our vision, and so we highly discourage it. Please refrain from uploading these models.
Your other models are neat! I especially like the planetary gears one. Please let me know if you have any questions.
