La plupart des modèles présentés ici sont des CAO de D-Central, mesurés sur le matériel de nos ateliers et publiés sous Creative Commons BY-SA 4.0. Lorsque nous adaptons une conception communautaire utile, sa fiche nomme le créateur d'origine, fournit le lien vers la licence d'origine et précise exactement ce que nous avons modifié.
Take the file and make it yourself. Change it, fork it, print it for customers. The only condition is credit and the same licence on whatever you build from it. If you would rather not print, we make every one of these parts in PETG — black or orange — and ship the finished article.
Ducting an ASIC? The D-Central shroud system carries the full shroud, silencer and ducting range with a machine-by-machine fitment table and duct sizing.
These files stay free. Forever. What pays for the next design is simple: buy the printed part, or fund the work directly. Either one puts the following model on this page.

Universal Single 120 mm Fan to 6″ Duct Shroud
One 120 mm fan mouth gathered into a single 6-inch collar. The 152 mm square base lands on the fan bolt pattern and the notched Ø152.4 mm crest flexes over rigid duct; 95 mm of shaped taper does what a flat plate with a hole in it cannot.
Universal Single 120 mm Fan to 8″ Duct Shroud
The same single 120 mm inlet opened out to an 8-inch outlet. The plenum grows from the fan mouth to a Ø203.2 mm collar across 115 mm of rise, so the section changes gradually instead of stepping at the duct joint.
Antminer S9 Single 120 mm to 6″ Duct Shroud
Cut to the Antminer S9 exhaust end rather than to a generic 120 mm square: a 152 × 176 mm mouth that clears the S9 case lip, then 150 mm of rise into a Ø152.4 mm six-inch collar.
Whatsminer 140 mm Fan to 6″ Duct Shroud
The 140 mm fan face on the M30S+, M50, M50S+ and M60, collected into a six-inch collar. A 154 mm square mouth over a Ø152.4 mm crest, 125 mm tall — the chassis face that 120 mm shrouds do not cover.
Whatsminer 140 mm Fan to 8″ Duct Shroud
The MicroBT 140 mm interface terminated in an eight-inch collar. The body widens to 203 mm square across 135 mm of height so the outlet is never the narrowest point in the run. M30S+, M50, M50S+, M60.
Antminer S19 / S21 Dual 120 mm to 6″ Duct Shroud
Two 120 mm fan mouths merged into one six-inch collar on a 250 mm base. Cut for the standard air-cooled S21 exhaust face, where the pair of fans feeds one shaped plenum instead of two open holes. Not the S21 Pro, not Hydro.
Antminer S19 / S21 Dual 120 mm to 8″ Duct Shroud
The standard air-cooled S21 dual-120 shroud with the outlet opened to a Ø203.2 mm eight-inch collar. 250 mm base, 170 mm tall, and the larger section is carried back into the plenum rather than bolted on at the end. Not the S21 Pro, not Hydro.
Antminer S19 / S21 Venturi Shroud — Dual 120 mm to 6″
Venturi body on the 250 mm dual-120 base: the plenum contracts to a throat before it opens into the Ø152.4 mm collar, so the two fan streams are merged under contraction instead of left to fight inside an open box.
Antminer S19 / S21 Offset Shroud — Dual 120 mm to 6″
Offset body on the 250 mm dual-120 base. The six-inch collar is pushed off the centreline so the duct can leave along a wall or past a rack upright without an elbow starting at the machine.
Antminer S19 / S21 Clamp-Groove Shroud — Dual 120 mm to 6″
Clamp-groove collar on the 250 mm dual-120 base: a groove turned into the Ø151.6 mm crest seats a worm-drive clamp, so the duct is captured mechanically and not held on by friction. 170 mm tall.
Antminer S19 / S21 Bayonet-Lock Shroud — Dual 120 mm to 6″
Bayonet collar on the 250 mm dual-120 base: lugs on a Ø157.2 mm crest twist-lock into the matching six-inch receiver, so the duct comes off in a quarter turn for service and goes back on indexed.
Antminer S19 / S21 Threaded-Collar Shroud — Dual 120 mm to 6″
Threaded collar on the 250 mm dual-120 base. A coarse Ø158.1 mm thread pulls the duct adapter down against the shroud face, giving a joint you can hand-tighten and re-tighten after a heat cycle.
Single 120 mm to 6″ Expansion-Chamber Shroud Silencer
An expansion chamber, not a foam box. The single 120 mm mouth opens into a 210 mm square volume 218 mm tall, then re-contracts to a Ø152.4 mm collar — the area change is the mechanism.
Whatsminer 140 mm to 8″ Expansion-Chamber Shroud Silencer
The 140 mm fan face expanded into a 230 mm square chamber 228 mm tall, then re-contracted to a Ø203.2 mm eight-inch collar. Chamber and outlet both sized to the larger fan.
Antminer S19 / S21 Dual 120 mm to 6″ Expansion-Chamber Shroud Silencer
Dual 120 mm expansion chamber on a 250 mm flange, 211 mm tall, exiting a Ø152.4 mm six-inch collar. Both fan streams expand into one volume before they re-converge.
Antminer S19 / S21 Dual 120 mm to 8″ Expansion-Chamber Shroud Silencer
The dual 120 mm expansion chamber with a Ø203.2 mm eight-inch outlet. 250 mm flange, 198 mm tall, the same expand-then-contract path scaled to the larger duct.
Antminer S19 / S21 Dual 120 mm to 6″ Shroud Silencer v2 — λ/4 Side-Branch
v2 adds a quarter-wave side branch to the dual-120 chamber: a closed stub tuned to blade-pass tone, standing the body out to 218.6 mm wide and 242 mm tall. Exits a Ø152.4 mm collar.
Antminer S19 / S21 Dual 120 mm to 8″ Shroud Silencer v2 — λ/4 Side-Branch
The λ/4 side-branch chamber with a Ø203.2 mm eight-inch outlet. The stub takes the body to 244.2 mm wide and 228 mm tall on the 250 mm flange.
8″ to 6″ Duct Reducer
Eight-inch duct into six across 89 mm of length, 208.8 mm at the wide end. A cone, so the section changes along the whole body instead of at one shoulder.
6″ to 4″ Duct Reducer
Six-inch duct into four across 89 mm of taper, 158 mm at the wide end. For the last leg of a run, where the volume no longer needs full section.
6″ Duct Coupler
Joins two lengths of six-inch duct. 158 mm across, 62 mm long — short on purpose, so the joint adds length to the run and nothing else.
8″ Duct Coupler
The eight-inch duct coupler: 208.8 mm across, 62 mm long. The same short straight-through joint, sized up.
6″ 45° Duct Elbow
A 45° turn in six-inch duct, swept rather than mitred, inside a 182.9 × 169.1 × 159.6 mm envelope. Half a right angle, for when a full 90 would over-turn the run.
8″ 45° Duct Elbow
The 45° sweep in eight-inch duct, 233.6 × 204.8 × 210.4 mm. Same swept centreline scaled to the larger section.
6″ 90° Duct Elbow (Compact)
A compact 90° turn in six-inch duct inside a 203.8 mm square envelope. The tight option, for a machine that sits close to the wall.
8″ 90° Duct Elbow (Compact)
The compact 90° turn in eight-inch duct, 249.2 mm square. Short envelope, for when there is no room to run a long sweep.
6″ Window Exhaust Port
A six-inch duct through a window sash, 39 mm deep. A plate with a collar, not a box — 210 mm square face, and the sash still closes on it.
8″ Window Exhaust Port
The eight-inch window port on a 248 mm square face, still only 39 mm deep. It sits in the sash gap without eating the room.
6″ to Dual 4″ Y-Splitter
Splits one six-inch run into two four-inch legs, with the divider shaped along the flow instead of butted like a tee. 226.3 × 152.4 × 198 mm.
8″ to Dual 6″ Y-Splitter
Splits one eight-inch run into two six-inch legs across a 335.8 mm body. The wye holds both legs on a shallow included angle so neither leg turns hard off the main.
120 mm to 140 mm Fan Adapter
Puts a 120 mm fan on a 140 mm opening. 140 mm square, 28 mm thick, both bolt patterns carried through and screwdriver access left clear.
140 mm to 120 mm Fan Adapter
The other direction — a 140 mm fan onto a 120 mm opening. 140 mm square, 28 mm thick, both patterns through-drilled.
120 mm Intake Filter Ring
Holds filter media across a 120 mm intake: 132 × 140 mm, 23.6 mm deep, with the media captured in the ring instead of taped across the grille.
140 mm Intake Filter Ring
The 140 mm intake filter ring — 160 mm square, 23.6 mm deep, with the media clamped in the frame rather than held down by the fan screws.
Threaded Collar Cap for Dual 120 mm to 6″ Shroud
Caps the threaded collar when the duct is off. Ø167 mm, 17.4 mm deep, onto the same coarse thread the duct adapter uses.
Antminer S21 Pro Dual 140 mm to 6″ Duct Shroud
Cut to the S21 Pro exhaust face: a 292 mm flange over its dual 140 mm fans, gathered into a Ø152.4 mm six-inch collar, 170 mm tall. Not the standard S21, not Hydro.
Antminer S21 Pro Dual 140 mm to 8″ Duct Shroud
The S21 Pro dual-140 shroud terminated in a Ø203.2 mm eight-inch collar. 292 mm flange, 175 mm tall. Not the standard S21, not Hydro.
Universal Dual 140 mm to 6″ Duct Shroud
Two 140 mm fan mouths into one six-inch collar. A 300 mm flange spans the wider fan pitch and the plenum rises 175 mm into a Ø152.4 mm crest.
Universal Dual 140 mm to 8″ Duct Shroud
The dual 140 mm body terminated in a Ø203.2 mm eight-inch collar. 300 mm flange, 175 mm tall, section opened along the plenum rather than stepped at the joint.
Antminer S19 Full-Wrap Dual 120 mm to 6″ Shroud
A full wrap, not a face plate: 296.8 × 213.5 mm of body that comes back over the Antminer S19 and S19 XP shell before it necks into a Ø152.4 mm six-inch collar, 190 mm tall.
Antminer S19 Full-Wrap Dual 120 mm to 8″ Shroud
The S19 / S19 XP full-wrap with a Ø203.2 mm eight-inch collar. The same 296.8 × 213.5 mm shell capture, opened to the larger outlet.
Antminer S17 Full-Wrap Dual 120 mm to 6″ Shroud
Full-wrap body cut to the Antminer S17 and S17 Pro shell — 303.4 × 196 mm of capture into a Ø152.4 mm six-inch collar. The S17e and S17+ carry a different face and are excluded.
Antminer S17 Full-Wrap Dual 120 mm to 8″ Shroud
The S17 / S17 Pro full-wrap with a Ø203.2 mm eight-inch collar, 303.4 × 203.2 mm of shell capture, 190 mm tall. S17e and S17+ excluded.
Avalon A15 Vertical Dual 120 mm to 6-Inch Duct Shroud
Built to the Avalon A15 vertical stack: its dual 120 mm face gathered into a Ø152.4 mm six-inch collar on a 250 mm flange. The interface comes off A15 / A15XP CAD and does not carry to other Avalon families.
Avalon A15 Vertical Dual 120 mm to 8-Inch Duct Shroud
The Avalon A15 vertical shroud with a Ø203.2 mm eight-inch outlet. Same A15 / A15XP-derived flange, larger collar. Other Avalon families use a different face.
Avalon A15 Vertical Dual 120 mm to 200 mm Metric Duct Shroud
The Avalon A15 vertical shroud on a Ø200 mm metric collar, Ø193.2 mm bore. A15 / A15XP interface only.
Antminer S19 / S21 Dual 120 mm to 150 mm Metric Duct Shroud
Dual 120 mm fans into a Ø150 mm metric collar on the 250 mm base, Ø143.2 mm bore, 165 mm tall. The metric answer to the six-inch shroud.
Antminer S19 / S21 Dual 120 mm to 160 mm Metric Duct Shroud
Dual 120 mm fans into a Ø160 mm metric collar on the 250 mm base, Ø153.2 mm bore. One step up from 150 mm without moving to 200.
Antminer S19 / S21 Dual 120 mm to 160 mm Metric Duct Shroud (Wide Base)
The Ø160 mm metric dual-120 shroud on the wider 260 mm flange. Same Ø153.2 mm bore, more seating area where the shroud meets the machine.
Antminer S19 / S21 Dual 120 mm to 200 mm Metric Duct Shroud
Dual 120 mm fans into a Ø200 mm metric collar on the 260 mm flange, Ø193.2 mm bore — the largest metric outlet this body carries.
Dual 140 mm Fan to 150 mm Metric Duct Shroud
Dual 140 mm fans into a Ø150 mm metric collar, Ø143.2 mm bore, on the 300 mm flange that spans the 140 mm fan pitch.
Dual 140 mm Fan to 160 mm Metric Duct Shroud
Dual 140 mm fans into a Ø160 mm metric collar, Ø153.2 mm bore. Same 300 mm flange, one duct size larger.
Dual 140 mm Fan to 200 mm Metric Duct Shroud
Dual 140 mm fans into a Ø200 mm metric collar, Ø193.2 mm bore, on the 300 mm flange. The widest metric outlet on the 140 mm body.
Antminer S21 Pro Dual 140 mm to 200 mm Metric Duct Shroud
The S21 Pro dual-140 shroud on a Ø200 mm metric collar, Ø193.2 mm bore, 292 mm flange. Not the standard S21, not Hydro.
Whatsminer 140 mm Fan to 150 mm Metric Duct Shroud
Metric twin of the Whatsminer shroud: the 140 mm fan face exits on a Ø150 mm crest with a Ø143.2 mm bore for metric rigid duct. 154 mm square mouth, 125 mm tall. M30S+, M50, M50S+, M60.
Whatsminer 140 mm Fan to 160 mm Metric Duct Shroud
The Whatsminer 140 mm face into a Ø160 mm metric collar, Ø153.2 mm bore — the size up from 150 mm when the run is long enough to want the extra section. 160 mm square body, 125 mm tall.
Whatsminer 140 mm Fan to 200 mm Metric Duct Shroud
The largest metric outlet on the Whatsminer body: a Ø200 mm crest over a Ø193.2 mm bore, on a 200 mm square shell only 125 mm tall. For M30S+, M50, M50S+ and M60 rooms plumbed in 200 mm duct.
Antminer S19 / S21 Dual 120 mm to 6-Inch Shroud — Wide Base
The dual 120 mm to six-inch shroud on the wider 260 mm flange — more seating area against the machine face and a longer landing edge, for the same Ø152.4 mm outlet.
Antminer S19 / S21 Dual 120 mm to 6-Inch Venturi Shroud — Wide Base
Wide-base venturi: the 260 mm flange with a contracting throat ahead of the Ø152.4 mm collar. Merging the two fan streams under contraction is what stops them stalling each other in an open plenum.
Antminer S19 / S21 Dual 120 mm to 6-Inch Offset Shroud — Wide Base
Wide-base offset: the six-inch collar moved off centre on a 260 mm flange, so the duct exits toward one side and the run starts straight rather than starting in a turn.
Antminer S19 / S21 Dual 120 mm to 6-Inch Clamp-Groove Shroud — Wide Base
Wide-base clamp-groove: a Ø151.6 mm crest with the clamp groove turned into it, carried on the 260 mm flange. The duct is captured by a worm-drive clamp seated in the groove.
Antminer S19 / S21 Dual 120 mm to 6-Inch Bayonet Quick-Release Shroud — Wide Base
Wide-base bayonet quick-release: a Ø157.2 mm lug crest on the 260 mm flange, mating the same six-inch twist-lock receiver. Duct off in a quarter turn, back on indexed.
Antminer S19 / S21 Dual 120 mm to 6-Inch Threaded Shroud — Wide Base
Wide-base threaded collar: a coarse Ø158.1 mm thread on the 260 mm flange, so the duct adapter screws down against the face and stays tight through heat cycling.
Antminer S19 / S21 Dual 120 mm to 8-Inch Shroud — Wide Base
Wide-base dual 120 mm to eight inches. The 260 mm flange carries the fan pair into a Ø203.2 mm collar — the largest imperial outlet on the dual-120 body.
Bayonet Duct Receiver 6-Inch — Twist-Lock Duct Adapter
The receiver half of the six-inch bayonet joint: a Ø152.4 mm socket with lug slots, 168.8 mm across and 45 mm deep. Twists onto any bayonet collar in the line.
Threaded Duct Receiver 6-Inch — Screw-On Duct Adapter
The receiver half of the threaded six-inch joint. Ø152.4 mm socket, 165.6 mm across, 50 mm deep — screws onto the threaded collars and gives rigid duct something to land on.
6-Inch Flex Duct Adapter — Rigid Socket to Flex Collar
Rigid socket one end, flex collar the other, 75 mm between them. Takes six-inch rigid duct into insulated flex without a wrap of tape doing structural work.
8-Inch Flex Duct Adapter — Rigid Socket to Flex Collar
The eight-inch rigid-to-flex adapter: Ø203.2 mm socket, flex collar, 75 mm long. Same joint, larger section.
6-Inch Flex Duct Window Vent Port
The six-inch window port terminated for flex: an insulated flex collar in place of the rigid socket, so the duct clamps straight to the sash plate. 210 mm face, 39 mm deep.
8-Inch Flex Duct Window Vent Port
The eight-inch window port terminated for flex duct. 248 mm square face, 39 mm deep, flex collar instead of a rigid socket.
8-Inch Long-Radius 90° Airflow Duct Elbow
The long-radius 90° in eight-inch duct: the centreline radius is opened right out, which costs a 304 mm envelope in two axes and buys a turn the air does not have to fight.
Antminer S19 / S21 Dual 120 mm Intake Filter Ring
One ring across both 120 mm intakes, 245 mm wide and 23.6 mm deep, so a single sheet of media covers the pair with no seam between the fans.
Antminer Full-Wrap Model Pack
Every full-wrap Antminer body in one download: the S9 single-120 shroud, both S17 / S17 Pro wraps (six and eight inch) and both S19 / S19 XP wraps. Five bodies, five shell captures, one archive.
Avalon A15 Model Pack
The complete Avalon A15 vertical set — the six-inch, eight-inch and Ø200 mm metric outlets on the same A15 / A15XP-derived flange. Three files, one interface.
Whatsminer 140 mm Model Pack
Every outlet we cut for the MicroBT 140 mm face: Ø150 mm, Ø160 mm and Ø200 mm metric plus six-inch and eight-inch imperial. Five shrouds for M30S+, M50, M50S+ and M60.
Antminer S21 Model Pack
The S21 family in one archive: both standard air-cooled S21 dual-120 shrouds, plus the S21 Pro dual-140 bodies in six-inch, eight-inch and Ø200 mm metric. Five files.
Nothing in this category.
Build Notes
Matériau
The whole line is PETG. When we build the finished part for you it comes in black or orange — orange being the D-Central colour.
Verify It
Every archive carries a manifest with the SHA-256 of each mesh, and the release publishes a checksum list beside the files. What you download is checkable against what we published.
Collars
Duct collars are cut to a crest diameter with a notched relief, so the collar flexes over rigid duct and springs back onto it. Every model names the outlet size its collar is cut for.
Fitment
Each model states the exact machines its interface was cut for. A family name is never a blanket claim — where a variant carries a different chassis face, the model says so and excludes it.

Dans quel format de fichier sont les modèles ?
Every model ships as STL, the open mesh format that every 3D printing toolchain reads. Nothing here is locked to a vendor, an account, or a proprietary container.
How big are these parts?
Each model card carries the real bounding box off the mesh, in millimetres. The ducting fittings and accessories are small. The full-wrap ASIC bodies are the largest things in the library and run past 300 mm on their long axis, so they are built in sections where that matters.
Quel matériau devrais-je utiliser ?
PETG, across the whole line — shrouds, silencers, ducting and accessories alike. It is what the models are drawn for and what we print them in. Order the finished part from us and it ships in black or orange.
Puis-je vendre des impressions réalisées à partir de ces fichiers ?
Oui. Les licences indiquées sur les fiches permettent l'utilisation commerciale. Créditez le créateur d'origine nommé et respectez les conditions du fichier : les originaux de D-Central utilisent CC BY-SA 4.0, tandis que BlockMit utilise CC BY 4.0.
Je n'ai pas d'imprimante 3D. Puis-je commander une version imprimée ?
Yes. Every model has an Order Printed button that goes to the finished part in our shop, built to order in PETG, in black or orange. Buying one is also what funds the next design in the line.
Ajouterez-vous d'autres modèles ?
Oui. La gamme de carénages, silencieux et conduits continue de croître à mesure que nous créons des interfaces pour de nouveaux appareils, et des conceptions communautaires utiles peuvent s'y joindre avec une attribution complète. Chaque fichier demeure gratuit sous la licence indiquée sur sa fiche.
Who designed these?
La plupart sont des CAO de D-Central Technologies, adaptées au matériel sur lequel nous travaillons. Les modèles d'origine communautaire sont identifiés sur leurs fiches. Le gabarit de poinçonnage de rondelles est une conception de BlockMit; D-Central ne revendique que sa validation, la préparation des fichiers et l'adaptation impériale du logement de rondelle.
Rather Not Print It Yourself?
We build every one of these parts to order, in PETG, in black or orange. Buying the finished article — or funding the work directly — is what puts the next design on this page.
