Nice but I probably don’t bother with this since I got a Bambu Smoke Purifier to connect with already.
Smoke purifier can restrict the airflow significantly, that can lead to elevated chamber temp and heat creep clogs on long prints. It was optimized for laser smoke, not for PLA/PETG filtering.
would you be able to link your version?
@maximit said he was working on a similar version, so to avoid stealing downloads away from him I would need permission from him to share his model. If he’s still planning on releasing it, it might be worth waiting for his anyway, it’ll probably be better lol. Mine is just a series of additions and modifiers put together in the slicer.

How do you figure that? I just got mine today and you can crank it up a crazy amount it will certainly not reduce airflow, if anything the other way around

Direct from bambu supports mouth:
Feel free to post it as a profile on the model. Sorry but I cant give you permission to post it as a separate remix, as the original design is not mine in the first place. If you want to post it as a remix please ask the designer of the original model.
Please note that when “upgrading” filters, adding a hose for external venting can introduce so much airflow resistance that your overall filtration may actually perform worse than the original setup.
To experience how air resistance works, try this simple experiment: take a PVC tube wide enough to breathe through comfortably and long enough so that you can submerge your body underwater while the other end of the tube remains above the water’s surface. While fully submerged, place the tube in your mouth and attempt to breathe normally—it will be surprisingly difficult. The same phenomenon occurs when you attach a hose to your printer: if you introduce additional resistance upstream of the hose, the airflow can fall well below the level you’d expect. Of course, this demonstration also involves other factors—such as hydrostatic pressure—but it clearly illustrates that the overall airflow resistance can be significantly greater than anticipated.

This is wrong. The internal fan wont even need to sweat. At 30% on the internal fan and the external fan turned off, it will still stay at 32c while printing petg with the air purifier installed. As if the external filter isnt even present. Didnt even trim down the hose.
This is not a guess. I actually did the testing and posted it in a review a week ago.
A small filter covering the exhaust port and sitting close to the fan, probably does cause resistance.
If cost is a factor.
Or, this will also do the job, if you dont plan on venting outside anyway,
Guaranteed this will be less restrictive and far more effective than the tiny filters going around.
Yea I saw the license for the original and I don’t want to get in trouble. It technically is a remix so I cannot upload it, even as a print profile. I don’t want to take any chances being reported. I’m happy to walk anyone who’s interested through the process of how I changed it though.
It should be fine as a profile on my model. Thats how I always upload remixes of models with standard digital license, I have like 5-6 different remixes out there like that, its not a problem. And I will certainly not complain, so feel free to post it.
Here is one example: H2D Hotend Box (A1 Compatible) - 6, 8 or 10 Slots by Maxx DesignMakerWorld: Download Free 3D Models
As a side note… bambu lab is kind of killing the remix culture by requiring “standard digital license” to collect the most points with exclusive models.
I’m assuming thats if the smoke purifier is OFF. If its on it would help to evacuate the air and keep the chamber cooler.
Not sure, best to ask @SupportAssistant
How about this, I’ll send you the 3mf and you can upload it. It’s not about the points for me, so I don’t really care about being the one to upload it lol. Just give me a shoutout in the profile description or something lol.
Just verify that it slices correctly after you open the file.
I run 2 of the 8" versions of that exact filter in my print shop and another of the 4" ones over my kid’s ferret cage - I’ll second that this is the way. They make a refillable one, too.

I’m almost ready to prototype a massive recirculating filter using the aux fan :D, these aux fans are a gimmick IMO, especially for such a big build plate.

Im planning to install a second AUX fan on the opposite side, I had that setup on my P1s and X1 and they worked great for overhangs and symmetric cooling with a special nozzle to spread the air to the whole plate. But mainly the AUX fan is there for added cooling for smaller items, I have all my filament profiles AUX turned down to 50% to prevent warping and I turn it up for smaller items, and turn it completely off for full plate items.

It’s gonna cover the nice big window on the right!
Here are photos of my old P1s, chamber heater, dual AUX (with special duct for full plate air) and bento box. Yes it will cover the window, but not a big deal.

I definitely need that! I never use the aux fan, so it just sits there begging to be converted into a bento box air scrubber
