PS: To clarify (if needed) what I mean by 'the flange': orient the piece as it would be if it were on the H960 (i.e. with the little interior tabs at the top, and the coloured panel on the front); the 'flange' runs down one side, along the bottom, and up the other side: it's a continuous piece,

From: Pete Turnbull z = about 0.5mm - you're trying to measure the taper on the edge of the flange? Not easy to be accurate. Ah, I've just realized I made a mistake in a previous message. I thought 'z' was calling for the distance between the inner edge of what I'm calling 'the

I've adjusted the drawing based upon some of the measurements provided, so far. However I'm not sure I interpret Pete's measurement of 33.1mm from the back of the flange to the front of the box, correctly. Noel also says the same 'from the back of the flange' so I must be missing something here.
