Centauri Carbon 2 Combo 3D printer External Enclosure

Clearview Plastics · Elegoo Centauri Carbon 2 Combo External Enclosure

Four materials.
One room to breathe in.

The Combo runs four filaments at once, and every one of them is loaded, buffered and switched outside the print chamber. The spool bank, the material path and everything the print gives off all share the air you are standing in. A machine's own shell is built to hold heat around the print. It is not built to hold air, and the stock filter was never engineered for it either.

The Clearview enclosure puts a controlled volume around the whole of it — printer, spool bank, filament path — with 120 mm ports for a filter or a duct run, and a 19-inch door on each side so a four-material machine stays as easy to work on as it was on an open bench. Bolt-on, CNC cut, 60 to 120 minutes to assemble, no modification to the printer.

The case for a second box

An enclosure around the machine isn't redundant. It's the half of the job the printer was never built to do.

A printer's shell holds heat around the print. An enclosure holds air around the printer — and then gives that air somewhere to go. Two different jobs. Two boxes.

GAP 01

The air has nowhere to go

Off-gassing happens at some level with every filament — PLA included. Contained air that never leaves the room isn't managed air. The enclosure concentrates it so a filter or exhaust can actually do something with it.

GAP 02

Four materials, four times the path

A multi-material machine loads, buffers and purges more than a single-spool printer does. All of that happens outside the print chamber, in the room, unless something is around it.

GAP 03

The shop gets in

Sanding grit, wood dust, metal chips, pet hair. A machine sharing a bench with a saw or a grinder pulls all of it through the motion system — and through four spools of open filament.

GAP 04

And then you open the door

Every seal on every machine fails the second you pull a part out. Inside a Clearview enclosure that moment happens in a volume that's still being drawn through the exhaust, not in the middle of your office.

What you're getting

01

02

03

06

01

Frame-less front door and top hatch

No frame between the two, so the front and top open as one span. Full reach to the plate and the machine without pulling a panel or moving the enclosure.

02

120 mm ports

Two on the rear panel, plus one on each side door you select, all cut to the same pattern. Any Clearview filter or ducting bracket mounts to whichever suits the bench; unused ports ship covered.

03

Interior LED lighting

Optional strip lighting along the top rails, so an operator can check a four-colour job through the panel instead of opening a door mid-print.

04

19-inch door on both sides

Access from either hand. It is what makes a four-material machine comfortable to work at — and the reason this one needs swing clearance on both sides, not just tabletop area.

05

Printed brackets and grommets

Panels bolt to printed corner brackets. A TPU fitting routes the Bowden tube and a wide grommet takes power and data through the panel instead of through a door gap.

06

Rear exhaust bracket

An optional bracket connects the rear port to 4″, 2.75″, 2.35″ or 1.75″ hose — so it fits a bench-top air purifier just as readily as a window run.

The whole material path, inside

Four spools, the buffers and the feed all sit in the same controlled volume as the print. Open the side door and the entire bank is in front of you at working height.

Printed brackets, real hardware

Panels bolt to printed corner brackets — print them from the supplied STL files or take the pre-printed black PETG kit. The printer's own power switch and ports stay reachable.

Ports

Ports where the bench needs them. One pattern.

Two on the rear panel, plus one on each side door you select, every one cut to the same 120 mm fan mounting pattern. Ports you are not using ship covered, so the enclosure is closed on day one and ready the day you change your mind.

• Every Clearview filter bolts straight on. Exhaust, recirculating or intake — all three land on the same pattern. Choose them when you configure the enclosure.
• Rear exhaust bracket, four hose sizes. 4″ for a window run, or 2.75″ and 2.35″ to meet an xTool or Creality bench-top purifier you already own.
• Build your own. 120 mm is an open standard, not a proprietary hole spacing. Any 120 mm fan, adapter or part you design and print bolts on without modifying a panel.
• Put the air where the bench allows. Intake low on one face, exhaust high on another, so you are not forced to run a hose across the front of the machine.

Filter on the port

The unit mounts flat to the panel on the 120 mm pattern — fan, carbon cartridge and duct as one assembly. Exhaust moves air out of the enclosure and outside through the window insert. Reduces fumes and smells.

Rear ports, out of the way

Two ports on the rear panel keep the hose run behind the machine rather than across the front of the bench. The rear exhaust bracket connects there.

Air management

The enclosure contains it. The filter is what mitigates it.

Those are two halves of one system, and they only work together. It is also why this enclosure is not gasketed — restrict the airflow and you neuter the filtration. All three mount to the port pattern and are selectable when you configure the enclosure. Pick the level that matches your space and your sensitivity.

Tier 01 — Exhaust

Exhaust Filter

Vents outside

Fan housing, 4″ hose and window insert, with carbon and HEPA. Moves air outside and reduces fumes and smells. The simplest setup of the three — needs exterior vent access and is slightly bulkier.

Tier 02 — Recirculating

Recirculating Filter

No window needed

HEPA and activated charcoal in a streamlined unit. No window required, reduces fumes and smells, and it holds chamber temperature. Honestly: under heavy high-temp use it isn't always a complete answer on odor.

Tier 03 — Commercial

Print Pro 3 by Donaldson

Commercial grade

Donaldson filtration with far deeper capacity than the other two. Absolute assurance on VOC and particulate mitigation. This is the answer when reduction isn't enough — occupied offices, clinics, labs, anyone who needs certainty rather than reduction.

Which one: for PLA and PETG, the intake and exhaust pair lets you dial in the enclosure temperature and vent straight outside through a 4″ hose. For ASA, ABS and above, the recirculating filter is the one — it keeps down fumes and smells with activated charcoal and HEPA while holding chamber temperature up.

On PLA

Most people assume PLA is completely benign. Our customers who are physicians, engineers, or running professional environments don't make that assumption. Off-gassing happens at some level with every filament. The question is just what level of management is right for your space and your sensitivity.

For institutional buyers

The paperwork your facility is going to ask for.

Schools, labs, aerospace and defense shops, shared makerspaces. The equipment clears the technical review and then stalls on documentation, because someone in EHS or facilities needs written evidence before a machine goes into an occupied room. Two documents solve that, and you can read both before you buy anything.

Available with the enclosure

Safety Documentation Pack — written for the Centauri Carbon 2 Combo, not for a category.

Three to five documents, depending on the machine. Not generic shop boilerplate — every one is rebuilt around this specific make and model, with its real specifications, hazards, airflow numbers and procedures. Delivered as editable Word files, so you add your logo, your facility names and your sign-offs. They take a machine from delivered in a box to defensible in a workplace.

For a lot of buyers this is the difference between "we'll look into it" and a purchase order.

Fitment and options

One size, cut to the machine — and it needs room to swing.

The enclosure

External dimensions

24″ W × 23.5″ D × 31.5″ H 610 × 597 × 800 mm

Minimum table top 26″ × 25.5″, rated to at least 120 lb, at a working height of 26–30″. At 31.5″ tall, a lower table keeps the top of the machine comfortable to reach.

The bit people miss

Side clearance

19″ doors, both sides they need somewhere to open

Plan the swing, not just the footprint. The generous doors on the left and right panels are what make this enclosure easy to work at. Don't wedge it between a wall and a shelf.

Outside this size, we build to size. Custom width, depth and height with the door, port and pass-through layout arranged around the workspace — same design, quoted per build.

Panel options

Base

White PVC with a clear acrylic front

A 1/4″ optically clear acrylic front panel so you can watch the print, with white expanded PVC on the sides, rear and top. Five-sided.

Upgrade

1/4″ commercial-grade panels

If you change one thing on the configurator, change this. Same thickness the whole way around, better fit, feel and finish — then pick the material that matches what you print.

• Full clear acrylic
• Smoked tinted acrylic
• Polycarbonate
• Amber orange

Clear acrylic is the best all-round choice. Smoked is the same panel with a quieter look. Polycarbonate trades scratch resistance for impact resistance. Amber orange screens UV.

Panel choice is the one option you can't change after the fact.

Who We’ve Worked With

FAQ

What is your return Policy?

We have a 30 day return policy. Unused, undamaged panels that still have the masking fully attached are eligible for a full refund less return shipping. If panels are damaged (after shipment) or the protective mask layer has been removed, we cannot offer a refund. For best results in ensuring fitment and to ensure you like the setup of our enclosures consider at least partially assembling with the mask on. If you find out it isn’t for you, this allows to get the return for a full refund.

Why would I order Polycarbonate vs. Acrylic?

Panel choice is the only feature on our enclosures that you can’t change after the fact. First things first, 1/4" is the best upgrade we offer—if you get nothing else, get 1/4" panels before upgrading anything else. Polycarbonate is impact resistant, while acrylic is scratch resistant. Acrylic is good for almost all filaments, including high-temp filaments like ABS, ASA, and PC.

Why would I go for a Recirculating Filter vs an Intake / Exhaust Setup?
Firstly, this will depend on the filaments you plan on printing with. For PLA / PETG, we recommend our Intake and Exhaust filters—this allows you to dial in the enclosure’s temperature and vent fumes directly outside with a 4" exhaust hose. For higher-temp filaments (ASA / ABS and above), our Recirculating filter shines, reducing fumes and smells with activated charcoal and a HEPA filter while keeping chamber temperature high.

There are some differences between your product pictures.

We update these often and as a small business it isn’t realistic to do a fresh photoshoot for every iteration. In general, function is always constant or better as we improve things. For the clearest indication of our current version, please rely on the renderings rather than the photos.
