Conventions
e Envelope and frame: SFF-8551's half-height device at its maxima (A1, A4), W at A5. Bottom face at z = 0, the connector end toward +X, the bezel at -X, the width centred; the bezel centred on the body both ways (SFF gives no offset).
« Mounting holes: M3 side holes in two rows and four bottom holes, a 90° countersink one pitch wider than D (SFF-8551 gives no lead-in), two full threads below it, then a 118° drill point. Simplified: plain bores at D, thread in the metadata.
e Connector: SFF-8523 Table 5-1: a block cw x ch on datum B's centreline, its centre cz up, its face in the end's plane; the keep- out under it open to datum C. No blades.
« House look: Illustrative: rounded edges, a chromate - zinc body with a label area toward the connector end (black label, the CommunityCAD mark cut through), a black bezel with a tray seam and an eject button inside A16.
