That’s not entirely true. They’ve just added support for 3rd Party Ventobox into the P2S Firmware.

To be fair: I wouldn’t necessarily call it a third party in the traditional sense; it’s a MakerWorld project. I don’t want to be nitpicky, but that makes a huge difference in the context.
Bambu has actually always supported projects from MakerWorld because they sell filament and components through their shop. Just click on the project, and the components will be added to your cart.
I’m sure there will be a Maker’s Supply Kit for this soon, too.
Did they add support for that product or any fan in general? (I use the term product here loosely)
PS I would have so many questions about this product. It looks neat, but Bambu would need to be careful endorsing a product that may or may not work as advertised, like are you using the correct type of carbon, size/volume/layout and similar questions for the filter. When do they need changed etc
It’s definitely 3rd party.
Although it’s available as print files on Makerworld, the original developer (Thrutheframe) has commercial deals with VOXELPLA and others to sell the physical product.
Bambu Lab have added support for this to the P2S firmware despite the fact they added a solution of their own in the form of the External Exhaust Kit.
The whole thing started as a MakerWorld project, didn’t it? Released 2025-11-07
What you’re showing me didn’t come along until much later, or did it not? This is the pre-assembled ventoBox, which the project creator later offered as an alternative. In other words: The project is still hosted on MakerWorld; it’s not really a third-party project.
The whole point of the discussion is that you can’t compare this to traditional third-party suppliers.
It is not uncommon for MakerWorld projects to be offered as kits on other websites as well:
The MakerWorld Project AURA is also available on other websites:
Why should I argue against that?
The focus was on the difference in treatment and support provided by Bambu towards third-party manufacturers compared to MakerWorld Projects. After all, you did bring up this topic. Of course, some third-party manufacturer accessories are officially supported, while others are not.
And just as a side note, as you can see for yourself, they sell it in their own store and make money off of it. That’s the difference compared to buying it on other sites, where Bambu doesn’t make any money.
What exactly are you planning to discuss? 
And while we’re on the subject: How does that relate to the topic: Setting the Record Straight on Cloud Access and Community? Maybe I missed something in your line of reasoning.
If you refer back you’ll see my original reply related to this statement:
Bambu Lab’s arguments and explanations only make the situation worse. They send a clear signal about the direction the company is heading in: a closed ecosystem where no third party is welcome. No room for improvement through third-party tools or components,
At least this part is factually correct, since there was a firmware update that excluded quite a few third-party manufacturers and developers. At most, one could discuss the word “no.” Anyone who pays Bambu will, of course, possibly get access to developer tools.
Many open-source projects had to be suspended on GitHub because certain features were blocked by Bambu. It also affected hardware such as PandaTouch, which subsequently became almost useless (though there are now projects attempting to revive it).
- On January 16, 2025, the 3D-printer manufacturer Bambu Lab announced that future firmwares for its 3D printers would introduce an authorization and authentication mechanism for printer connection and control, in the name of security. The change restricted the use of third-party accessories and slicers such as Panda Touch and OrcaSlicer, and it gated print initiation, motion control, fan and hotend control, AMS configuration, calibrations, remote video, and firmware upgrade behind a Bambu-issued authentication path.
And once again, the question: Do you see it differently? What would you like to discuss about this?
Funny enough, the same Obxidian nozzle for H2D stopped working with the latest FW.

As an additional information: the corresponding forum thread.
I feel like Matter Hackers and E3D have gone dark on this. I gave up fighting getting Bambu Lab to admit it worked before their firmware update (which it did - was a fact) and they have make no mention of fixing their optical algo that reads the nozzle, nor have I gotten feedback on getting nozzles that DO in fact work on the H2D in all lighting conditions from E3D or the vendor I bought the nozzles from.
Yeah, but I’m not sure what else we shall do with that. I feel like I should have opened a chargeback with PayPal right after that FW change with E3D.
It’s been several months and it’s saddening to see E3D just ghosting everyone with that.
Bambu Lab’s recent explanations don’t really ease concerns — if anything, they highlight a shift toward a more closed ecosystem where third‑party tools and community contributions have less room to exist. That doesn’t make anyone “anti‑Bambu.” It just makes people pay attention.
I genuinely like my Bambu A1. It’s a great printer. But I’ve paused buying from the Bambu store because the long‑term direction matters just as much as the hardware itself. And the reason people are cautious isn’t fear or speculation — it’s because we’ve seen similar patterns play out across other tech products.
Other companies have made similar decisions that ended up hurting long‑term customers:
Imagine you bought TiVo set‑top boxes in Australia (I bought 3). They relied on TiVo’s cloud. Then the company shut the servers down, and the hardware instantly became unusable. No local fallback, no offline mode — just a product that stopped working because the vendor walked away.
Now imagine you own several Bambu printers. They only work with authorised slicers. LAN mode becomes limited or removed. Firmware updates require cloud login. Then the company changes direction, introduces subscriptions, or restricts third‑party slicers entirely. Suddenly your printers depend on decisions you can’t control.
And again, this isn’t a far‑fetched scenario — we’ve already seen similar moves across consumer tech:
-
Sonos pushed an app update that removed key features and broke local playback, leaving expensive speakers dependent on a cloud service that suddenly didn’t work.
-
Google shut down “Works With Nest,” breaking thousands of smart home integrations people relied on for years.
-
Philips Hue reduced local API functionality and nudged users toward cloud accounts and subscription‑style services.
-
Fitbit shut down Pebble after acquiring it, leaving perfectly functional watches without the cloud services they needed.
-
Logitech disabled the Harmony Link remotely, turning a working device into e‑waste overnight.
-
Wink introduced a mandatory subscription or the hub would stop functioning.
-
SmartThings shifted more automation to the cloud, breaking local routines and third‑party integrations.
-
LIFX and other smart bulb vendors pushed updates that removed LAN control, making basic lighting dependent on cloud servers.
-
August and other smart lock companies restricted local APIs and introduced subscription fees for remote access.
-
DJI uses geofencing and cloud‑based restrictions that can prevent drones from flying even when the owner has legitimate reasons.
These aren’t fringe cases — they’re mainstream companies making decisions that reduced user control over products people had already paid for.
That’s why people are cautious with Bambu’s direction. Not because they dislike the printers, and not because they’re imagining worst‑case scenarios, but because the pattern is familiar. Once a company closes its ecosystem, users lose leverage, and the hardware becomes dependent on business decisions rather than personal ownership.

You can always just close the tab and never come back here, if you don’t like these discussions.

Ive heard that the only reason they did this is because bambu was “borrowing” some IP from e3d, for their older nozzles. Sort of a , dont sue me and I’ll let you sell some too situation.Since they’ve changed the design, I imagine the e3d partnership will come to an end. With the new direction for filtration, they wont need voxel either. Don’t stand on the shoulders of titans… Use them like a staircase only until you no longer need them, then make your community think you invented everything. It really helps when you pop up right after input shaper and PA become useful and allow all printers to double or triple in speed. People that dont understand, will think they got fast and good because of the x1

OMG i forgot about sonos. What a vipers nest. Those guys had the balls to sell a physical speaker you cannot connect via any wiring, nor via generic bluetooth, only via their stupid little app… And got away with it! Consumers should be legally allowed to throw those speakers thru the Sonos factory windows
