<p>I'm currently working on making a cosplay prop of a Fallout 4 Laser Rifle. Much of it I'm 3D printing due to easy access and quite frankly a lack of spare time to really handmake much of it. One thing that I'm curious about now is the barrel of the gun itself, a very segment of square tubing with rounded corners, preferably around ~4.5" in width based on how I've modeled the back of the gun so far.</p>

<p><a href="https://i.sstatic.net/N2RaZ.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/N2RaZ.jpg" alt="Fallout 4 Laser Rifle"></a></p>

<p>The first thing that came to mind here was some sort of prefab tubing, either like metal ducting or a PVC/plastic pipe. However, these either proved to be prohibitively expensive or nearly nonexistent in the size I needed.</p>

<p>Does anyone have suggestions on where I could get/easily manufacture a square tube like this with rounded corners?</p>

Mostly Off-the-Shelf (or at least quite easily fabricated) Rounded Square Tubing?
