Whatsminer 140 mm Fan to 6" Duct Shroud
Whatsminers use 140 mm fans, which means the enormous supply of 120 mm shrouds on the market is useless to you.
Whatsminer 140 mm Fan to 8" Duct Shroud
The 140 mm Whatsminer shroud with an 8-inch outlet. If you are going to duct a machine that moves as much air as an M-series does, this is the size that stops the duct being the bottleneck.
Antminer S19 / S21 Dual 120 mm to 6" Duct Shroud
Two 120 mm fans merged into one 6-inch duct. This is the single most-asked-for shroud in the modern Antminer world, because the S19 and standard S21 both put a pair of 120 mm fans on the exhaust end and neither of them gives yo...
Antminer S19 / S21 Dual 120 mm to 8" Duct Shroud
The dual-120 Antminer shroud with the outlet opened to 8 inches. Two fans at full power genuinely can use the extra cross-section, and this is the version to reach for whenever the duct run is doing more than going straight thr...
Antminer S19 / S21 Venturi Shroud — Dual 120 mm to 6"
The airflow-first member of the dual-120 family. Instead of stepping the plenum straight down to the collar, the venturi profile contracts and then re-expands through the throat, giving the merged air stream a smooth path rathe...
Antminer S19 / S21 Offset Shroud — Dual 120 mm to 6"
Sometimes the duct cannot leave from the middle. A shelf above, a wall behind, a neighbouring machine, a window that is not where you would have put it — the offset shroud moves the collar off centre so the duct exits where the...
Antminer S19 / S21 Clamp-Groove Shroud — Dual 120 mm to 6"
A worm-drive band clamp on a smooth collar will slide if the duct gets pulled. This version cuts a dedicated seat into the collar so the clamp has something positive to sit in, with a reinforcing band around the groove so the c...
Antminer S19 / S21 Bayonet-Lock Shroud — Dual 120 mm to 6"
A quarter turn on, a quarter turn off. The bayonet collar exists for people who take the duct off regularly — for maintenance, for moving machines, for seasonal changes in where the heat is supposed to go — and who are tired of...
Antminer S19 / S21 Threaded-Collar Shroud — Dual 120 mm to 6"
A coarse-pitch threaded collar, so whatever goes on the end screws down positively and stays there.
Single 120 mm to 6" Expansion-Chamber Shroud Silencer
A shroud with an acoustic job on top of the ducting job. Instead of taking the fan straight to a collar, the air passes through a reactive expansion chamber — a deliberate volume change that reflects part of the sound energy ba...
Whatsminer 140 mm to 8" Expansion-Chamber Shroud Silencer
The Whatsminer answer to the same problem. A 140 mm fan face on the intake, a reactive expansion chamber in the middle, an 8-inch duct collar on the way out — sized so the acoustic chamber does not become the airflow bottleneck...
Antminer S19 / S21 Dual 120 mm to 6" Expansion-Chamber Shroud Silencer
Two 120 mm fans, one merging plenum, one reactive expansion chamber, one 6-inch duct.
Antminer S19 / S21 Dual 120 mm to 8" Expansion-Chamber Shroud Silencer
The dual-120 silencer with an 8-inch outlet, for the installs where you want the acoustic chamber but cannot afford to stack its pressure penalty on top of a restricted duct run.
Antminer S19 / S21 Dual 120 mm to 6" Shroud Silencer v2 — λ/4 Side-Branch
The tuned tier. Version 2 keeps the reactive expansion chamber of the original and adds a quarter-wavelength side branch — a closed stub whose length is chosen so that sound at its target frequency arrives back in the main duct...
Antminer S19 / S21 Dual 120 mm to 8" Shroud Silencer v2 — λ/4 Side-Branch
The top of the silencer line: the tuned quarter-wave side branch of the v2, with the 8-inch outlet that keeps the pressure penalty sane on a serious duct run.
8" to 6" Duct Reducer
A tapered step from 8-inch duct down to 6-inch. Not a plate with two holes — a proper cone, so the air changes diameter gradually instead of slamming into a shoulder.
6" to 4" Duct Reducer
The small end of the reducer family. Tapers 6-inch duct down to 4-inch, which is the size that PSU exhausts, small enclosure fans and tight wall penetrations actually want.
6" Duct Coupler
The most boring part in the catalogue and the one people need most often. Joins two lengths of 6-inch duct end to end, with a centre stop so both sides seat to the same depth and a barrel long enough to actually clamp.
8" Duct Coupler
The 8-inch version of the joiner. Same centre stop, same clampable barrel, sized for the trunk lines that carry a serious machine or several smaller ones.
6" 45° Duct Elbow
A gentle 45-degree turn in 6-inch duct. Two of these make a 90-degree turn that costs meaningfully less pressure than a single sharp 90, which is the sort of trade that decides whether a long duct run works or disappoints.
8" 45° Duct Elbow
The 8-inch gentle turn. On a trunk line carrying real airflow, the difference between gentle and sharp bends stops being academic — this is the fitting to reach for first whenever the run has to change direction.
6" 90° Duct Elbow (Compact)
A right angle in the smallest envelope we could give it. This is the space-constrained option: for when the duct has to turn hard against a wall, behind a rack, or under a shelf, and there is simply no room for the gentler alte...
8" 90° Duct Elbow (Compact)
A full right angle in 8-inch, kept as compact as the diameter allows. The fitting for trunk lines that have to turn hard because the building says so.
6" 90° Duct Elbow — Airflow Variant (R/D 0.94)
The right angle you use when you actually care about the airflow. Instead of turning as tightly as the fitting can be made, this one carries a centreline bend radius of 0.94 times the duct diameter — a sweeping turn rather than...
6" Window Exhaust Port
The part that ends the run. A flanged 6-inch port designed to sit in a window opening or a cut panel, so the exhaust leaves the building through a proper fitting instead of a length of flex duct wedged under a sash.
8" Window Exhaust Port
The 8-inch termination. Same flanged through-panel design as the 6-inch port, scaled to the trunk size that a hard-working machine or a shared exhaust line actually needs.
6" to Dual 4" Y-Splitter
One 6-inch trunk, two 4-inch branches, joined by a shaped wye rather than a tee.
8" to Dual 6" Y-Splitter
The big wye. One 8-inch trunk, two 6-inch branches, for the installs where a single duct run has to serve two machines or one exhaust has to feed two destinations.
120 mm to 140 mm Fan Adapter
Puts a 140 mm fan on a 120 mm mounting. A bigger fan moving the same air spins slower, and a slower fan is a quieter fan — which is the single most effective noise change available to most home miners that does not involve buil...
140 mm to 120 mm Fan Adapter
The other direction: a 120 mm fan on a 140 mm mounting. Less about acoustics, more about logistics — 120 mm is the size the world actually stocks, in every speed, bearing type and static-pressure rating you could want.
120 mm Intake Filter Ring
A retaining ring that holds filter media over a 120 mm intake fan. Dust is what kills mining hardware slowly — it insulates heatsinks, clogs fins, and turns a machine that was running fine into one that throttles for no visible...
140 mm Intake Filter Ring
The 140 mm version of the intake filter ring — the size Whatsminer M-series hardware and most large-fan builds actually need, and one that is annoyingly hard to buy off the shelf.
Threaded Collar Cap for Dual 120 mm to 6" Shroud
A screw-on blanking cap for the threaded-collar shroud. Seals an idle machine’s exhaust in a couple of seconds, and comes off just as fast when the machine goes back into service.
Antminer S21 Pro Dual 140 mm to 6" Duct Shroud
The S21 Pro moved to a 140 mm fan pair, which quietly made every dual-120 shroud on the market useless for it.
Antminer S21 Pro Dual 140 mm to 8" Duct Shroud
The S21 Pro shroud with a full 8-inch outlet. On a machine with two 140 mm fans running hard, this is the version that should be the default and the 6-inch one the exception.
Universal Dual 140 mm to 6" Duct Shroud
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 machi...
Universal Dual 140 mm to 8" Duct Shroud
The universal dual-140 body with a full 8-inch outlet. Two 140 mm fans is the highest-airflow configuration in common use, and this is the version that does not throttle it at the very first fitting.
Antminer S19 Full-Wrap Dual 120 mm to 6" Shroud
The full-wrap S19 shroud. Where the standard dual-120 part covers the fan pair, this one wraps the entire exhaust end of the chassis — so the air that escapes around the fan frames, out of the corners and past the edges gets ca...
Antminer S19 Full-Wrap Dual 120 mm to 8" Shroud
The full-wrap S19 shroud with an 8-inch outlet — the configuration that takes containment seriously at both ends.
Antminer S17 Full-Wrap Dual 120 mm to 6" Shroud
A full-wrap shroud for the S17 generation — hardware that has been written off more than once and is still hashing in workshops and basements everywhere.
Antminer S17 Full-Wrap Dual 120 mm to 8" Shroud
The S17 full wrap with an 8-inch outlet. On a generation of hardware known for running hot and losing hashboards to heat, giving the exhaust the largest practical path out is not an upgrade — it is the sensible default.
Antminer S19 + PSU Spill-Lip Shroud to 6"
The most complete single-piece capture in the line. A full S19 exhaust-end wrap, extended by a 30 mm lip along the side to catch the spill coming off the power supply — the heat that a normal shroud leaves behind because it is ...
Antminer S19 + PSU Spill-Lip Shroud to 8"
The flagship. Full S19 exhaust-end wrap, 30 mm PSU spill lip, and a full 8-inch outlet — the most heat this line captures in one piece, going out through the largest duct it terminates in.

Conseils d'impression
Matériau
Le PLA convient à la plupart des boîtiers. Utilisez du PETG ou de l'ASA si la pièce se trouve près d'une source de chaleur comme l'échappement d'un ASIC.
Hauteur de couche
0,2 mm offre un bon équilibre entre vitesse et qualité. Utilisez 0,12 mm pour les pièces d'exposition visibles.
Remplissage
Un remplissage de 15 à 20 % suffit pour les boîtiers et les supports. Augmentez à 40 % et plus pour les supports structurels qui portent du poids.
Supports
La plupart des modèles sont conçus pour s'imprimer sans supports. Consultez les notes du modèle si des supports sont nécessaires pour certaines orientations.

Dans quel format de fichier sont les modèles ?
Tous les modèles sont fournis en fichiers STL, la norme universelle de l'impression 3D. Les fichiers STL sont compatibles avec tous les principaux logiciels de tranchage, dont Cura, PrusaSlicer, Bambu Studio et OrcaSlicer.
De quelle imprimante 3D ai-je besoin ?
Toute imprimante FDM avec un volume d'impression d'au moins 200x200x200 mm convient à la plupart des modèles. Les options populaires incluent la Bambu Lab P1S, la Prusa MK4 et la Creality Ender 3 V3. Le Space Heater XL peut nécessiter un volume d'impression plus grand.
Quel matériau devrais-je utiliser ?
Le PLA convient à la plupart des boîtiers et supports puisqu'ils ne sont pas près d'une chaleur directe. Pour les pièces exposées à l'échappement d'un ASIC (comme les boîtiers de chaufferette), utilisez du PETG ou de l'ASA pour une meilleure résistance à la chaleur. Évitez le PLA standard pour tout ce qui est près de températures soutenues supérieures à 50°C.
