Universal Dual 140 mm to 6″ Duct Shroud

Description

Overview

The model-agnostic dual-140 shroud. It references the two fan flanges rather than any particular chassis, which makes it the part to reach for on hardware we have not built a dedicated shroud for, on custom builds, and on machines that have been through a fan swap.

What it fits

Designed around a pair of standard 140 × 140 mm fan flanges on a shared exhaust face. Because it is dimensioned to the fans rather than a specific chassis, it carries across a wider range of hardware than a model-specific shroud — at the cost of not wrapping any one machine as closely.

Measure before you order. Fit dimensions in this line are derived from published fan and chassis geometry and are not yet validated against measured production hardware. Check your flange size and the clearance around your machine against the footprint in the specifications below. If something does not fit, tell us — that is how the next revision gets better.

How it is used

Use it on dual-140 machines without a dedicated shroud, on custom and rebuilt units, and on anything that has been converted to 140 mm fans with our 120 to 140 mm adapters. Standard 6-inch collar on the outlet keeps it compatible with everything downstream.

Why it helps

Model-specific parts are better when they exist and useless when they do not. There is a long tail of hardware, rebuilds and one-off conversions that will never get a dedicated shroud, and a universal body dimensioned to the fan pattern is how that tail gets served at all. It is also the honest choice when you are not certain what generation a machine actually is.

• Dimensioned to the fan pattern, not to one chassis
• Covers custom builds, rebuilds and fan-converted machines
• Standard 6-inch collar for full downstream compatibility
• Single continuous body, no assembly

Specifications

Open source — print it yourself, or buy it finished

Every shroud D-Central designs is released as an open file. The geometry for this part is free to download from our 3D models download center: use it, modify it, remix it, run it in your own shop, sell what you make from it. There is no licence to buy and no design gated behind a purchase. Shared knowledge is the whole reason this industry has open hardware at all, and we are not going to be the ones who stop passing it on.

This listing is for the finished part: made to order in PETG and shipped from Montreal, Quebec. If you would rather have it in your hands than spend an evening making one, buy it here — that is what pays for the next design in the line. You can also support the open-source work directly through D-Central’s fund page.
