Joining faces in a model I recently started dabbling into 3d printing. I extracted a model from a old game, but I noticed that the faces of the model are not 'glued' to each other, they are basically standalone faces near other faces to make the model, how can I make the model a solid or how to join 2 faces to do it to the whole model manually?
Select all vertices, right click and then select merge, merge by distance, which should do just as you want.



Hope this helped!
