Naked edges due to missing surfaces can easily be corrected by filling in the hole with a new surface and joining the new surfaces together. Re-topology is the best option, since it will generate a clean mesh for 3d printing and will consume less time then removing unwanted cubes, . Two suggestions: remove a few faces, or one at time, until repair body will show the thing in smooth. A Handle on Life – Broken Drawer Handle Fix Hackaday. For non -planar holes, different strategies will need to be employed. Check your tolerance is set correctly in your rhino file.
