I'm a student in college working on a project, and have relatively little experience with Solidworks so please bear with me. My teacher gave me a mesh file, which I converted to a solid body. I then split it into segments, added female/male pegs for connections, and printed two out. I then realized that it would be more realistic for me to have this part be hollow for cost and time sensitivity reasons. However, due to the complex geometries, I can't use the shell function properly. I can't alter the geometry of the object much, because the final product will be used for laboratory testing of shear force from fluid and dispersion. Is there any possible way for me to go about hollowing out this object?
