Do: The 400 mm MGN12H LDO-SLR12H-400Z1 has 16 holes. Mark holes 2, 4 … 14: every other hole from the second, so both end holes stay open. Slide in 7 M3 T-nuts, ~15 mm clear of each end.
Check
7 nuts, one per marked hole, flat; holes 1, 15 and 16 unmarked; clear slot at both ends.
What you're looking at
The D extrusion is the X beam, the one the toolhead runs along. It carries an MGN12 rail, wider than the Y rails because it holds the toolhead off one carriage. Same T-nut rule: load them before the XY joints cap the ends.
