separate parts

So I know in the description for silver, it says that multiple parts are not permitted.
However, when printing components for a hinge, I uploaded an .obj with 3 separate parts;
-a pin
-the main jewellery piece
-a piece that will clip in

And I received no errors.
Would I get the error as it was checked over at order time?
Or is Shapeways allowing the pieces due to their tiny size?

I believe the automated check is for more basic things like bounding box size limits (both maximum and minimum), material thickness, and other fundamental properties. I don't think it looks for violations of "mulitple part" rules and such.

Correct, if you order, it should fail when it goes through a manual check.
