Stackable Rack for NVIDIA DGX Spark. Built for running multiple NVIDIA DGX Spark units in one footprint, this rack holds two devices per tier in a two-wide layout. Open front and rear keep QSFP, RJ-45, USB-C and HDMI ports reachable, and stacked tiers add capacity without replacing existing parts.

Keyed Joints Lock Every Tier. Each tier locks onto the next with 8 x 8 mm self-locating chamfered keys molded into the tops of both end walls and the center divider. Keys seat into matching sockets above, carrying the load straight down through three columns to the feet, so extra capacity just means stacking another identical tier.

Built From Twenty Separate Parts. The stack breaks down into twenty printed pieces: two end walls and one center divider per tier, two floor trays per tier fastened with M3 screws, four press-fit feet at the base and flush top caps on every column. No part is tier-specific, so the same pieces build any size stack.

Open Access, Matte PETG Build. Printed in PETG with a fine, consistent layer finish, the rack keeps its front and rear fully open so QSFP, RJ-45, USB-C and HDMI ports stay reachable on every installed device. A 0.394 inch center divider and 0.157 inch end walls form the load-bearing spine, with open airflow between tiers.
