Hi Sven, so just to make sure I understand, the file "1488A13_Surface-Mount Hinge with Holes.STEP" is the one from McMaster-Carr with the structure you like where the hinge is made up of individual separate objects which can be rotated independently?

And the file "GS_19_150_0_A8_MA8_A8_OA8_4.stp" is the one you don't like, because things like washers, nuts and bolts are all combined together instead of being independent pieces?
