This is a dynamite looking set of armor, Steve,and although your goal is only Basic approval, with a few upgrades you could be the first trooper with 3D printed armor to reach EI! I can't begin to wonder how much time you spent sanding and filling those pesky print lines, but the end result is truly spectacular, sir.
If I could make a few suggestions, the first would be is that I agree with Reese about the calves.
It's difficult to tell from the photos how large your calves actually are, but there seems to be quite a bit of room on the sides (photo 2). The ones seen in the film had more of a taper rather than being so large at the top, making them look more like those seen on a Clonetrooper.

Just an FYI, andI'm sure it will not affect approval at Basic, but the width of the hexagon on the sniper knee looks quite a bit wider than those seen onscreen.
The designer of the files that this was printed from obviously has a keen eye for detail, but it needs some need tweaking. As seen below the indented line around the TD plate has curved corners, and the raised "O" does not have those little projectiles on the top/bottom and is more of a rounder shape rather than an oblong. The positioning of the "buttons" that face the rear? You NAILED it!

Overall I would give this build a 9.5, Steve. I'm danged gad to see that someone has stepped up to the plate and finally shown us that 3D armor has truly earned it's place. Well done, sir!
