Instructions
I'm guessing you'll want to print this with the Z axis running parallel to the beam, which is not how it is in the model; sorry about that, I'm a baby to the world of 3-d.
The dimensions are 10x10x100mm, so the Z axis should be 10mm long. I'll post a shorter beam, later, so that people can try scaling it up to 15x15mm; I think it might work better in its own right at that scale. Obviously we think 10x10mm will be plenty for aluminium!
