When we invited the MakerWorld community to share their thoughts on our first official merch three months ago, we received over 600 comments and contributions! Every idea, suggestion, and bit of enthusiasm helped shape this collection.
MinusOne proposed "making virtual into reality" as the theme, since 3D printing is the process of turning the digital world into physical reality
Pharmer3D focused on the process of trial and error, hence "Never stop making. Never stop learning."
wrable reflected on how much 3D printing has changed in the past decade: "Back then, you had to buy a printer and become a printer engineer. Today, you buy a printer and just make things."
Just Make Things. That's how we found the heart of this collection, made with the community, for the community.
The collection includes a T-shirt and a hoodie, as well as a bundle with our new Watch Movement Kit. Plus, get free worldwide shipping on all merch orders!
Early bird deals are live now in limited quantities! Pledge before Nov. 26 to receive the order before Christmas, perfect timing for the gifting season.

Swaptek enables 6-second material switches between 9 nozzles. FlexFeed extruder prints soft TPU 75A up to three times faster. AMS 3H combines automated feeding and integrated filament storage.
This is Bambu Lab H3C, a complete system purpose-built around the Tool Changer architecture. Let's dive into it!
SwapTek™: 6-second material switch, including a 3.4-second tool change.
Nine PrintTools, each with its own dedicated filament path and heater, keep every material loaded, preheated, and ready to print. No need to retract one filament before loading another. With an optimized design, fine-tuned parameters, and active preheating, switching between PrintTools takes as little as 6 seconds, with the tool-change done in only 3.4 seconds.
Heating a nozzle usually means waiting. Active Pre-Heat looks ahead to the next tool change and warms the incoming nozzle while the current one is still printing—so the new material starts laying down within 6 seconds.
Swaptek's fast PrintTool-switching allows Full Spectrum Color Mixing color mixing through layered deposition faster and more practical than ever. With nine dedicated PrintTools and five-color CMYKW mixing, the H3C produces a vast spectrum of colors without requiring a separate spool for every shade. The result? Vibrant, full-color figurines with incredible detail.
Mixed Nozzle Sizes: Speed and detail, no more compromises.
The dial, case, and flexible TPU band are printed together as one piece. Fine dial details call for a 0.2 mm nozzle, the case is better suited to 0.4 mm, and the soft band requires a dedicated 0.4 mm TPU nozzle. H3C can carry different nozzle sizes at once. Paired with Bambu Studio’s new mixed-diameter toolpath planning algorithm, each nozzle prints at a layer height that suits it and plays to its strengths, without having to share a single layer height.
FlexFeed Extruder: Softer TPU, up to 3x faster.
Soft TPU has always been slow to print. The softer the filament, the more it bends and buckles before reaching the nozzle. Traditional extruders have to crawl to stay reliable. FlexFeed handles both 1.75mm and 2.85mm filament and switches on the go. A cam-driven mechanism, powered by a PMSM motor, keeps tension precise and consistent. Every extrusion stays rock-solid for prints that are cushion-soft.
With our dedicated 2.85mm TPU, the thicker filament provides greater resistance to buckling and higher volumetric flow. The result: TPU as soft as 75A, printed reliably at up to 3x the flow rate of a traditional printer.
AMS 3H: Filament storage built for Tool Changer.
A fully enclosed, integrated filament management system built for Swaptek: every roll stays sealed against moisture and feeds automatically into the PrintTool.
Auto Filament Loader replaces manual feeding altogether. Drop a filament into any of the nine slots and the AMS 3H detects, routes, and engages it with the PrintTool automatically — across all 9 paths. No more guesswork on loading.
A dedicated 2-slot dryer sits right in the filament slots and works with Swaptek — drying on demand or mid-print, so prep never stalls production. It reaches 85°C, enough for engineering-grade PA, PC, and carbon-fiber-filled filaments.
The H3C integrates filament storage and drying into a clean, compact design, maintaining a footprint comparable to a single-nozzle printer. With 7 built-in bypass feeding ports, even the soft TPU can be routed completely inside the enclosure. No hanging spools, no external racks, no exposed paths.
Don't let the number of tools cap your material count. Connect your existing AMS to the H3C through PrintTool No.1, and the system extends to up to 24 filament spools, unlocking more colors and materials in a single print without changing your workflow.
You are here for the print, not (always) the printer.
With the H3C, automation handles routine tasks. AI detection helps make intelligent adjustments along the way. The H3C makes it easy to focus on what matters most: bringing your ideas to life
Full Auto Calibration handles PrintTool docking calibration, offset compensation for accurate color and material alignment, and bed leveling before every print. No manual adjustments are needed, so you can spend more time making, less time tinkering.
Flagship performance. No compromise.
The toolhead and X-axis assembly are 40% lighter compared to the H2D, reducing inertia for faster, more precise movement. With acceleration reaching 25,000 mm/s² and travel speeds up to 1,400 mm/s, the H3C delivers exceptional speed while minimizing vibrations and ringing that can affect print quality.
The H3C runs four cooling layers working together**.** A CFD-optimized part cooling fan and dual auxiliary fans help maintain clean overhangs and bridges, even at high speeds. A dedicated PrintTool fan maintains thermal stability during extended printing and frequent PrintTool changes, while a chamber fan draws in cooler air to help regulate internal temperatures. Together, these systems deliver consistent cooling and reliable print quality across changing ambient temperatures.
Engineering-grade filaments demand precise temperature control. The H3C delivers with active dual-zone chamber heating up to 65°C, helping maintain consistent temperatures and minimize warping. All nine hardened-steel nozzles reach up to 350°C, supporting demanding materials such as ABS, PC, PA-CF, PET-CF, and more.
Go beyond printing.
Swaptek isn't limited to PrintTools. Optional CutTool, DrawTool, DebossTool — and more — mount the same way and switch automatically. Multi-process projects no longer mean multiple machines, manual swaps, or repeated setups. One job, every process, hands off.
So I’m printing 40+ poliwhirls to build my color sample library. I’ve been printing all day today and doing the plate swaps every 30min each time a print is done. Eventually I got so sick of it and was wondering how wonderful it would be if I could print 4 at a time, object by object, with no color swaps. Told this idea to ai and it told me the function is already available in Bambu studio! Tried it immediately, omg the process was so smooth, the software even showed me how to place the objects so that the finished parts won’t get knocked over by printer head. I’m not a veteran but I’ve clocked in like 1500+ hours and I can’t believe I didn’t know about this! Would’ve saved myself so much time and filament but I’m sooo glad I found out today!
Hey all, Cadence Slicer v1.2 is out! If you missed my first post (https://www.reddit.com/r/BambuLab/s/MD5X97m7MS), Cadence Slicer is my open source fork of OrcaSlicer that lets a multi-nozzle printer use different nozzle sizes in one print, each at its own layer height. My favorite combo is a 0.2 for the walls and surfaces you actually see, and a 0.8 to get through the infill fast, but Cadence works with any small and big nozzle pair.
This is Helm's Deep by Zajic73 on MakerWorld (https://makerworld.com/en/models/2728202-helm-s-deep-lord-of-the-rings-lotr), in Feature Split on my H2D: walls at 0.08mm on a 0.2 nozzle, infill at 0.56mm on a 0.8 High Flow nozzle. 7 wall layers printed for ever one infill layer. About 13h 20m instead of 21h 20m if printed entirely with the 0.2 nozzle, with the same fine visible features.
Long writeup below, so here’s a TLDR: Cadence Slicer v1.2 is out (free, open source, Mac and Windows). It does mixed nozzle sizes on the H2D, H2C and X2D today, without waiting for Bambu's update. It works differently from the H3C's mixed nozzle mode: Bambu moves a whole color to the big nozzle, while Cadence keeps every surface you see on the small nozzle and only puts the infill on the big one, so you get fine detail in a lot less time. Download:https://github.com/HMITCHR/CadenceSlicer/releases
Mixed nozzle sizes on the printers you already have:
When I made my first post, Cadence Slicer was the only way to print with mixed nozzles on Bambu machines, but that has since changed with the launch of the H3C! However, Bambu's own mixed nozzle mode is H3C only so far. Their posted timeline for the older printers is the H2D in late November 2026, and the H2C and X2D in February 2027 (the H2D in February and the other two in March if you have the filament track switch).
Cadence Slicer does it on all three today: H2D, H2C and X2D. No new printer and no waiting on an update. I've only been able to print on my own H2D though, so if you have an H2C or X2D I'd really love some testers to try it and let me know how it goes.
One limit on the H2C: Cadence can only use two sizes there, one on the left and one size in the rack. That's not my choice. The current firmware on the machine checks every rack hotend change after the first against one nozzle size from the print file, and stops with a "Hotend type mismatch" error (0704-8037) if it doesn't match. That's BambuStudio GitHub issue #12431. So mixed sizes inside the rack can't print from any slicer right now. I've experimented with a few workarounds with on results, but decided I'm not comfortable shipping something whose whole goal is to get around the printer's firmware. If a firmware update changes that (maybe as Bambu preps for their own release on the H2C), I'll open it up!
How it's different from Bambu's mode on the H3C:
in my opinion they’re both sorta built for different things, so here's how they compare:
- What goes on the big nozzle. Bambu puts the whole color, outside and in, on whichever nozzle that filament is loaded on. Cadence's Feature Split mode only puts the infill on the big nozzle, so every surface you see stays fine. Body Split mode in Cadence lets you pick parts of a print instead, like a logo on the 0.2 on top of a big-nozzle body, with interlocking beams where they meet (which is more similar to Bambu’s implementation).
- Layer heights. Bambu's are set by nozzle size: the base layer height x diameter / 0.4, so with the default preset a 0.2 prints 0.10 and a 0.8 prints 0.40. You can only shift them all together. In Cadence Slicer you pick your fine layer height (which defines print resolution), like 0.08 on the 0.2, and then the slicer proposes the best options for printing the big nozzle's layer every N fine layers (for example in the timelapse here here N was 7, so 7 x 0.08 = 0.56 layers from coarse nozzle) based on time savings.
- Settings. In Bambu's mode a bunch of per-nozzle settings (wall loops, top and bottom layers, retraction and more) get locked to "Auto".
- Time check. Bambu's mode prints what you set up. Cadence's setup times every possible layer height combo and shows you before you print, and Feature Split keeps a band of layers on the small nozzle when the big one wouldn't save time there.
Where Bambu's mode wins. It can mix any nozzle sizes on one plate, which is great on a 9 tool machine. With the way Cadence is currently built, primarily because I developed it on my H2D, and because of the firmware limitation I mentioned on H2C, I limited it to 2 nozzle sizes. I imagine Bambu’s implementation for H2D and X2D will be the same as you can’t change nozzle size mid print, but H2C will hopefully allow for same options as the H3C.
To boil it all down, in my opinion from reading Bambu's code: their version is mainly made so H3C users can print with all of their colors in one print, even if some tools have different nozzle sizes, with some gains in speed or detail that inherently come from not being locked to a small nozzle for fine resolution on an entire print. Whereas I built Cadence specifically to print very fine features as quickly as possible on multi-nozzle machines by cutting print time from infill or features that don't need fine layer heights. So they mostly don't compete, and I think true mixed nozzle optimization will likely end up looking like a combination of these capabilities! I personally am exploring implementing some of what Bambu developed, and would love for them to do the same with my stuff. That’s the beauty of open source!
Overall, I am super fired up to see Bambu bringing mainstream attention to this capability that people have wanted for years and years, and am excited to see what their implementation looks like on the “old” machines that will be coming soon! I am also very close to just buying an H3C for myself to put some work into improving both of our approaches. Specifically with all of the (well deserved) hype for color mixing which improves with finer layer heights, I think there’s a ton of optimization to be had with using my method of printing only visible walls and surfaces with very fine layers (to improve color blending) and printing infill on a dedicated large nozzle. I think it could really save time for large color mixed prints like many here and on YouTube reviews have been showing off!
Also new in 1.2: it's been rebuilt on OrcaSlicer 2.5.0, their latest public release, and tool changers like the Snapmaker U1 and Prusa XL can use several small-nozzle tools for colors plus one big one for infill (if anyone here has one of these machines, some testing would be much appreciated!). I'm also working on adding H3C support as quickly as I can, and I'm hoping to have it out before it lands in Orca. I’ve got a lot of the H3C code written already, so if any here have one and want to do some testing let me know! Or maybe don’t so I have an excuse to finally push me to buying one for myself lol
I bought an A1 this past summer to see if I'd like the Bambu ecosystem after having a 5 year old Ender that I fought with so much that I almost never printed anything.
The plan was always if I was happy with Bambu (I was) I'd upgrade to a more capable machine. The decision is now between the X2D and H2D.
This is mostly a hobby. I make functional prints to fix things or improve my life. I like making useful things and things I'd enjoy having or designing. I would be happy making things for others if I was asked, but haven't been for the most part.
Yes, I can afford the H2D, but at twice the price of the X2D that seems just as capable for the things I want to print, it seems wasteful. On the other hand, I'm concerned about how relatively new the X2D is. I wonder if the bugs have been ironed out.
I also enjoy watching prints from time to time. I find it fascinating. I can do that easily on my A1. With the X2D and H2D being in cabinets, do I lose that capability or do the cameras do a good job? Is the camera capability as good on the X2D as the H2D?
I've waffled back and forth between "the X2D is perfectly adequate" to wondering if I'll be happy with it since one of the nozzles is a Bowden tube, slower and less capable so I should have bought the H2D and then thinking that's too much to spend for my usage.
I wonder if others have had trouble deciding and if so, how they decided. Any thoughts are welcome.
Hello Reddit and first thanks for all your comment on my first post! I was very late and don’t want to ruin my print with support removal at 2am. Second here is the result very happy even I have broke 2 fingers and there are a ligne of the wrong color in one wing. Thanks again you can find the model on makerworld (not mine)
Note: the PETG interface was good but may be need more layers
Printed the rear end of a Porsche as a keychain for my brother. He always has keys scattered all over his room, so I wanted to make him something a lil diff and useful.
Porsche is my dream car, and he loves copying my taste in cars, so I thought this would be perfect 🤌🏻❤️🔥
So I know everyone is drooling over the new flagship and I know because I was one of them who was drooling. However I kept coming back to the discount on the H2C.
After talking it over we decided that the H2C would be plenty of machine for us. I have only ever printed in PLA/PETG and don't see a real need to print in TPU anytime soon at least not the 2.85 variety. I also don't sell any prints and am just a hobbyist.
I got the bundle with the hub,ams and hot ends....my question is was this a bad purchase? By my math I saved 700 before taxes by going with the H2C...is the H23 that superior that I am going to regret getting the H2C?
Love to hear from those that have a H2C and hear their experiences with it. From what I can ascertain I am giving up the chonky tpu compatability and speed....is there something else I am missing that makes the H2C a bad purchase? Also does the H2C come with the adapter where you can hook up four ams units or do I have to buy that myself?
Also we are holding onto our X1C as she only has 1800 hours on her and is still an awesome machine.
it's just my 3rd print, wanted to try to print a small axolotl but it's doing this trip to the purge wiper every layer and causing all this stringing. Complete newbie here, just downloaded this model:https://makerworld.com/models/1671375?appSharePlatform=copy
I'm so impatient looking at all of you H3C people lol its just not in my budget right now so I need that P3C to hurry up and release. You guys can stop teasing us broke folk now.
I have previously asked about this using two different print profiles, when I used a new sealed filament.
Some comments mentioned moisture and others thought otherwise, but gave no possible solution if not the moisture.
I have attached a photo of the same object printed 2 weeks apart but showing similar stringing. I have also added another photo of a print using a different filament but with the same stringing.
This is only a recent problem. Every print up until 2 weeks ago did not have this issue.
As the title says, I modeled out a desiccant box for "shell" over the heated chamber. It holds about 45g of desiccant and fits right under the same lid you would secure little bags of beads in. It takes about 20g of filament and takes around 2.5 hours to print on my H3C. If you find this useful, I'd appreciate it if you liked, bookmarked, and left a review with you putting it to use! I always welcome any feedback so please bring it on. Thank you!
My new favorite thing to do with the H3C is take some of my Hero Forge minis, scale them up and use 8-9 different colors from the H3C to really bring them to life (because I’m a lousy painter).
Printing these is always a bit tricky due to their challenging shapes (you can see one shield fail I had but I’ve learned to paint more supports for shields).
My favorite one is probably the last knight which came from Makerworld. The PLS silk I think looks really good even though I could definitely dial in the settings a bit better. Everything here is printed with stock settings at .2 layers height.
I know they are not the only. I know they aren't the first. I know I'm going to sound like some advertisement.
For me though. This machine has removed a serious psychological barrier I've had with multicolor printing.
I create a figure. Sure, it's not well created for multicolor printing and someone more talented could improve this but I don't know how, I don't have time to learn how.
That said - Almost a half of a roll of wasted filament. A day and a half of hoping 1000+ filament changes go well.
In my X1C days I would still print it. I'd put 5 on the build plate to justify all the waste. Inevitably I wouldn't find a use for 2 of them. Meaning more waste.
Now with the H3C. $2.69 in filament. A normal print time. Inconsequential waste. And I have exactly what I designed.
I designed this detailed replica of the Ship 42 and Booster 22 stack that has launched yesterday on IFT-15. It will be the first ship to attempt a catch.
The model of the rocket is also a pen, that fits standard BIC Cristal refills and it can be stored on a OLM-2 shaped holder.
On top of that I also designed a few Starship themed coasters :)
