How do you "fill" a hollow space between two fill surfaces in complex geometry

the back corners ive left one side as far as i could get with extrudes and the other with the fill surfaces in place, however if i intend to 3d print, the surfaces leave a void in the slicing software so i need to fill them, im stumped, ive tried deleting faces, sketches wont work as everything is curved, i cant seem to make anything loft as there are so many vertices it breaks.

any ideas?

I would use a variation of the atomic fillet. Just create a big block that goes through that area. Delete those surfaces to create a surface model with easy to fill holes. Use fill or loft to close the holes, and Enclose to make a volume.

Can you use the enclose feature?

no, it seemed to fail, i watched every video i could, and different examples, i may still be doing it wrong, but it still wont generate an interior, im tyrying to troubleshoot, there may be microscopic places where lines dont meet or faces overlap somewhere. the fill command works fine to cover the surfaces.
