Antminer S9 shroud that ducts the 120 mm exhaust fan into 6-inch line, with a 150 mm deep body drawn around the S9 chassis end instead of a flat plate on the fan. Turns an old S9 into a heat source you can aim. Made to order in PETG in Montreal, Quebec; the design is open source.

Use the S9 cluster to route legacy miner owners to specs, repair guidance, APW3 power parts, hashboard bundles, and heater use cases.
This Antminer S9 shroud ducts the machine’s 120 mm exhaust fan into 6-inch line, and it is the part that gives an S9 its second career. The S9 refuses to die. It is the most widely owned mining machine ever built, it costs almost nothing now, and most survivors run somewhere they were never designed for: a garage, a workshop, a shed that needed heating anyway.
What stops that working is not the hashrate. It is that an unducted S9 owns the room it sits in — heat everywhere, noise everywhere. Put a collar on the hot end and duct on the collar, and the machine becomes a heat source you can aim: at a workshop bench in January, out a window in July.
This one is drawn around the S9 exhaust end rather than the fan alone: a 150 mm deep body that takes in the end of the chassis, so air is collected as it leaves the machine instead of being clipped at the fan face.
Drawn around the Bitmain Antminer S9 exhaust end — the fan-end panel and the 120 mm exhaust fan behind it — and it wraps that panel rather than clipping to the fan flange. The S9i, S9j, S9k and S9 SE carry the same exhaust-end panel, so the same body seats on them; an S9 variant rebuilt on a different enclosure is outside what this part is cut for. The outlet is a standard 6-inch duct collar.
Nothing on the machine changes to fit it: the stock fan stays, no wiring is disturbed, and the chassis goes back to standard in a minute.
Shrouding a bare 120 mm fan, a PSU fan or a bench build instead? The Universal Single 120 mm Fan to 6″ Duct Shroud is cheaper and more flexible. Two 120 mm fans on one face, as on an S19 or S21, want the Antminer S19 / S21 Dual 120 mm to 6″ Duct Shroud. A full-wrap body is a different part again — see the Antminer S19 Full-Wrap Dual 120 mm to 6″ Shroud.
An S9’s exhaust fan sits recessed in the chassis end, and the chassis is wider than the fan. Clip a flat adapter to the fan flange and the corners of that end stay open: hot air finds them and spills back into the room. A body that takes in the whole end face collects that spill and returns it to the stream.
The 150 mm depth does a second job: square-to-round is a change the air has to make somewhere, and depth is what lets it happen gradually rather than as a step.

The S9 has stayed alive because people keep modifying it. This body is released under CC BY-SA 4.0 through the 3D models download center: free to download, modify, remix, print and sell, with nothing gated behind a purchase. Hardware this old should not need a proprietary bracket to stay useful.
D-Central Technologies drew this wrap in-house and open-sourced it: ours, published, not borrowed. The card for it sits at the S9 shroud entry, and the file is antminer_s9_single_6in.zip — the STL, the CC BY-SA 4.0 licence and the installation and safety guide, all of it free.
Buying the listing gets you the finished body, printed to order in PETG in Montreal, Quebec and shipped from Canada, ready to slide onto the chassis. Black or orange, the two colours the line runs in. Buying the printed part, or backing D-Central’s fund page, is what pays for the next design.
See the full D-Central shroud and ducting system for the compatibility matrix and sizing guide.
It is drawn around the Bitmain S9 exhaust end and its 120 mm fan, which is the panel the S9i, S9j, S9k and S9 SE also carry — the same exhaust-end geometry, so one body seats on all of them. What it is not drawn for is an S9 variant rebuilt on a different enclosure. Aftermarket fan swaps that keep the 120 mm face are fine.
Capture. The universal shroud mounts to the fan flange, which is right on a bare fan or a bench build. On an S9 the chassis is wider than the fan, so a flange-mounted part leaves the corners of the exhaust end open to the room. This body takes in the whole end instead.
That is what most of these get bought for. Duct the exhaust into the space you want warm in winter and re-route to a window port in summer — the same shroud serves both. Keep the run short and unkinked, and give the room a path for air to get back in.
Nothing about this part touches the electronics. The stock fan stays fitted, no cable is unplugged, no firmware is altered, and the shroud sits on the outside of the chassis. It comes off in seconds and leaves the S9 exactly as it was.
A shroud and duct move the noise rather than absorb it, and sending it out through a wall is most of the practical win. To work on the sound itself, the Single 120 mm to 6″ Expansion-Chamber Shroud Silencer puts a volume between fan and duct, the standard way to take the edge off fan tone.
No. This body is for the exhaust end, where the heat and most of the noise leave. The intake end is better served by a 120 mm Intake Filter Ring, which keeps workshop dust off the boards without restricting the machine’s supply of cool air.

When Bitmain announced the Antminer S21, the Bitcoin mining world took notice. After years of incremental improvements across the S19 lineup, the S21 represents a genuine generational leap…
In the rapidly evolving world of cryptocurrency, Bitcoin mining has emerged as a cornerstone activity for enthusiasts and investors alike.
Industrial mining hardware was never built for your house. 3D printing closes the gap — shrouds, enclosures, stands, and repairs. Here is what to print, what to buy, and where the limits are.
