GB10 / DGX Spark & ASUS Ascent — Splittable Side-Vent Duct + Parametric Rack Ears

GB10 / DGX Spark — Splittable Side-Vent Duct + Modular 10" Rack Ears

A remix of **"2 x Node Nvidia DGX Spark (GB10) Cluster Side Vent Cooling

Duct" by Henry Thomas** — thanks for the great base model!

Fits GB10 boxes: NVIDIA DGX Spark and ASUS Ascent GX10.

 ⚠ Not yet test-printed

The first print is still pending. This is verified in CAD only

(watertight meshes, B-rep interference/fit checks) — not physically

printed and fitted yet. Clearances (joints, captive nuts ~0.2 mm,

ear-to-body fit) are best-effort and may need tuning. Feedback welcome;

I'll update once printed.

Why this remix

I couldn't fit the original duct on my Prusa MK4S in one piece, so I

split it into two printable halves and added a solid way to rejoin them.

What's new

- Two-part split through the chamber center (vent/funnel on the left

half) — fits MK4S and CORE One.

- Click + screw rejoin: tongue & groove (interior stays flush) + 4

outside bosses with captive M3 hex nuts (slide a nut in, screw from

the other side — stronger & reusable than self-tapping).

- Modular 10" rack mount: 2 rack ears slide into the duct and lock

with one M3 screw; captive M3 nuts in the ears too. Flip-symmetric.

- STEP + parametric FreeCAD included for remixing/re-tuning.

What to print (one 2-node unit)

- 1× duct-split-left + 1× duct-split-right

- 2× rack ear (right + left, or print right 2× and flip)

- 2× riser (per device — Asus Ascent riser included; DGX Spark riser in

the original) + 2× filter-baffle (original parts)

Hardware

M3 hex nuts + M3 screws (seam bosses + ear fixation). Orient each duct

half seam-face up. PETG/ABS/ASA recommended for heat.
