Small piece of rectangular section steel wanted

Hi. I’m after a small piece of rectangular or square section hollow steel tube.

The internal dimensions need to be at least 70x45. It needs to be only about 50mm long. Ideal wall thickness is probably 1.5mm. These dimensions can vary a bit. Basically, it just needs to be able to fit a GoPro clone, preferably fairly tightly.

I’ve looked in Bunnings etc but not found anything suitable. A few places will sell me 3meter lengths but I’m too parsimonious to buy that when I need only 60mm.

In case you’re wondering, I need this to make a deep water GoPro housing. I occasionally do some drop-camera underwater photography, and would like to get down deeper where the bigger fish roam. You can see a video of mine here.

Another issue is that I have limited facility to machine steel, so if I could get it cut perfectly square on at least one end, but preferably both, then it will save me a lot of work.

So anyone know where I can purchase such a thing.

Cheers
Arron

I can help you with this, I have 75x75x4, or 75 x 100 x 4. And there will be other sizes if I really look hard. I can weld a plate on one end or whatever. I’m sending a PM with my number.
