This is a complete model of the rifle from the Mandalorian in the series called: "The Mandalorian". It is obviously not perfect, but it has my own take to it. Otherwise, it is pretty much exactly the same.
This model does require a couple parts, which include: a metal rod with a 1 inch diameter and one with a 1/3 inch diameter. (25mm and 10mm will also work). I just went to my local home office store and found them there. Or you can order them off of amazon.
Edit: I added the rods as an .stl file, they are pretty long though so it may be hard to print.
I had also made this compatible with TonyBloke's model of a belt clip to hold the rifle. So credit to him for making that.
I had some help designing the small details from a friend, Knowledge_Sponge_OG, on Reddit, if you would follow him there.
