Is there an easy way of removing unwanted features from a meshed 3D scanned part with well defined edges to prepare it for 3D printing?

Question

I am working with a part that was taken from a *.acs point cloud map to a meshed part through Autodesk ReCap. This object had hidden features that I was unable to erase (or see) when converting from a *.acs (point cloud), to a *.rcp (ReCap file) to a *.obj (mesh), and I have not found an intuitive way to remove the "flash" from the sides without creating holes that I have not been able to fill. I tried manually removing these edges in MeshMixer and Meshlab, but feel like there must be an easier way than what I have tried so far. Image for reference

Thanks!
