Flat aluminum stock in that orientation will have very little resistance to bending side-to-side. Once it's clamped on the ski, it'd be plenty rigid and would self-align/self-straighten to some extent, but I'd worry about dropping the thing or putting something heavy on top of it on my workbench and bending it. Any reason you can't make the side rails with a right angle extrusion to give you rigidity in both the horizontal and vertical plane? Having the angle profile would also make for more surface area to contact the two end pieces. With the right sort of profile in the two printed end pieces, I imagine you could significantly simplify the hardware/attachment components. Just a L-shaped slot that the aluminum angle fits into and a set screw or two to hold it all together.
The other question I'd have is about the consistency of the adhesive tape measure. It seems like it would be a non-trivial thing to line two tape measures up exactly in the same place on every set without some sort of visual reference to make the assembly easier.
