Stackable Tray for Two DGX Spark Nodes. Built for home-lab racks running two NVIDIA DGX Spark nodes side by side. Top dovetail rails and bottom slots let each tier slide-lock onto the next, secured by a rear thumb screw, so builders stack additional tiers vertically as their compute cluster grows, no extra brackets needed.

Two bays, one slide-lock stack. Left and right base modules form two open bays sized for one node each, joined at the center by the tie plate. Male dovetail rails run along the top edges; a matching female slot on the underside lets the next tier slide on from the rear and lock with the thumb-screw stop keys.

Five parts, one assembly. The tier breaks down into five printed pieces: the left and right base modules, the interlock tie plate that joins them at the center, and two slide-lock stop keys, left and right, that seat in the rear dovetail slot to keep a stacked tier from sliding loose.

Vented walls, clean finish. Both outer end walls carry a row of tall airflow slots for passive cooling, while the center divider and floor deck are solid. The tie plate and stop keys seat flush against the base modules, with a fine layer finish and precise seams at every joint.
