It can be assemled fully and works well by the supplied Stl but optionally a pin can be incerted throgh it to strengthen the construction further. See the preview pictures for reffrence on assemby. The files also include a solid model where the doors can't open. This is meant for faster prints of the model for uses where the doors doesnt need to be opened.
