<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use DB;

class Tbl_Perimetro extends Model
{
puplic function perimetros(){
$carteras = DB::table('tbl_perimetros')
        ->join('tbl_equipo_postventaatcs', 'tbl_equipo_postventaatcs.id', '=', 'tbl_perimetros.postventaatc_id')
        ->join('tbl_lista_carteras', 'tbl_equipo_postventaatcs.carteras_id', '=', 'tbl_lista_carteras.id')
        ->get();

return $carteras;
}
}

If you just want to use query builder you could to do so. But I realy recomend to use eloquent methods. Also, is important to look about mutators, appends and scopes options to models that could help you more than query builder alone.

Other appointments:

• DB::table('tbl_perimetros') could be replaced by $this in this model
• Do not forget return for the method.
• Try protect $appends = ['perimetros'] and rename method to getPermietrosAttribute to return perimetros as an item in model object.
