Hey, first post on here and I'm completely new to 3D printing. Myself and a friend want to do a 3D print of a Boeing 747 nose at a 1:72 scale. The issue is the model we're using is ported from a game and the geometry is a mess, full of overlapping vertices and other issues. Is there a quick way to fix this without manually bridging each vertice? I've attached a sample of the file we're dealing with, thanks in advance!
