    Hien,

    This particular square tubing was the smallest I could find. The inside opening It is a bit larger than the Astra IIIB stud but still snug. The dimensions are:

    Outside Face         .125"      3.175mm

    Wall Thickness      .015"      0.381mm

    Inside dimension   .095"      2.413mm

    Again, I found this square tubing in a hobby shop that had mostly trains and railroad scenery items such as trees, lighting fixtures, people and  ... brass structural elements like tubing, beams and plates for building bridges, towers or simulating cargo on railroad cars.
