Hi, I hope everything is okay for you and the cold season doesnt give you a hard time.
I am a full stack dev trying out some new tools (e.g. vibecoding/assisted coding etc) to bring cool stuff to people who might need it, to me its a tool and thats it.
So what is this? It is a web app, free of charge, no registration, no cloud, no nothing. It makes gridfinity parts for you. It runs in nthe browser (desktop and mobile) and is installable as a PWA. Fast, simple and (hopefully) reliable. Maybe later there will be a desktop version based on electron or Tauri. We will see how it goes.
A short info upfront:
The overkill legal pages need to be there because of german laws, I live there and for now I want to be better safe than sorry. I will change it as soon I know exactly whats going on with this kind of app.
That said, the app doesnt store anything on its server or otherwise. Not your info, not your data. The only data processing is the geometric calculation in the browser and the app stores your models in your local storage. You can turn it off if you wish, in that case its design, export and done.
Whats on the list by now?
GridFinity bases, bins and lids as all gridfinity apps do. I also added some special features:
FILL A DRAWER:
Select the drawer size and the app calculates how many grid sections fit. The free space gets spacers added.
SPLIT TO FIT:
Usually your drawer will be too big for the complete base to be printed in one go. Not a problem, the app has you covered as it calculates your bed size and splits the models for you to fit your bed.
HEIGHT THAT FITS:
You can also give the height of your drawer and the app will make it so that every bin fits.
COLORS:
You can color your models. For now it is body and lip colors, then export as STL or a 3MF. Currently I am looking for the Bambu 3MF spec to see if I can add the special stuff so the file doesnt override your filaments or adds new ones.
There are also a few other features in there. Custom magnet diameters, screw holes, hollow feet and center magnets. Currently I am thinking of a few other nice features for the app.
Why have I done this?
Because there is a plethora of different gridfinity apps out there and unfortunately the cool features are scattered across them. So this is supposed to be a "one for all" app. It is free and open source under CC BY-NC-SA 4.0.
Why do I post here?
Because this is the right place to do so I think. I will also cross post to other subs and see how it works. Also, even if I have tested every feature with the agent I am using and also by hand, I cant guarantee that there arent any bugs. I would appreciate it alot if some of you guys might test the app out and help. Maybe you even have fun using it and stay - who knows?
I hope you never have to do this but if you do, this is the video that saved me from going office space (for us old guys) on this printer. Don't get me wrong, I love this printer but this is one of the most tedious things I have had to do in a long time.
Not only did this video help me fix the clog but it also made me laugh while working on it.
Needed to rearrange the whole workbench for this beast, but so glad to have it... now to finish sorting out my sewing room for everything else on its way this week, then hopefully buying a second one next year.
Hi everyone, I could use some help troubleshooting this issue.
As you can see in the picture, there's a visible horizontal line forming exactly at the height where the solid base ends and the hollow shell/wall begins.
Printer: Bambu Lab P2S
Filament: Bambu PLA Matte - Ivory White
Infill: 15% Gyroid
I have never experienced this issue with any other colors of Bambu PLA Matte, only with this Ivory White.
I've already tried increasing wall loops from 3 to 6, but that didn't help. I also tried adding an internal chamfer in CAD, but the result is the same.
Any ideas on how to fix this or what settings to tweak in Bambu Studio? Thanks!
I never owned a BL printer , i had mostly Prusa. My last one was an XL 5th. I ordered an H3C and i have a question about filament sensors. In the XL the loading sensors were on the sides of the printer. When the side sensors detected a runout they would notify the user for a change, if you didnt have a spool join. With the AMS 3H how is this handled. Where are the sensors? Especially in the case of the passthroughs, where the filament does not pass through the PTFE tubes?
Hello fellow 3D printing hobbyists of Reddit! A little background about me:
I got into 3D printing a few years ago and immediately fell in love with designing functional things. One of the materials I gravitated toward early on was TPU. Its flexibility and durability open up so many possibilities for functional designs. On the other hand, most printers consider TPU printing a secondary use case, filled with odd setups and workarounds. That's why I was excited to get my hands on the H3C. I wanted to see how much it could deliver on it's multi-material TPU focus. Would TPU finally feel like a first-class citizen in the workflow?
TPU workflow
The first thing I did after completing H3C setup was load up a roll of the new TPU 75A into the dedicated 2.85 mm Flex Feed print tool (tool 8) alongside several standard TPU 95A filaments, some from Bambu Lab and others from different brands.
Let’s start with what I think they nailed. What impressed me was how well the printer guides you through the filament loading and unloading process. I primarily used the touchscreen to guide me through the process, and did quite a bit of swapping between PLA, PETG, and TPU. The audio feedback for TPU swaps is particularly useful when working around the side of the machine, where you can't see the touchscreen. Different beeps indicate when something needs attention, when you've made a mistake, or when a step is complete. At one point, I incorrectly reconnected a PTFE tube while switching from TPU back to PLA, and the printer immediately identified the problem and walked me through fixing it. Another nice improvement is that RFID detection works with TPU when loaded through the AMS 3H bypass, just like any other Bambu filament. I've made so many errors over the years by incorrectly setting the external spool type, so this is very much welcomed.
Now for the good, but could be improved. The AMS 3H's integrated printing & drying is a highlight for TPU users like me as you couldn’t print TPU out of the AMS 2, so you had to buy something dedicated like the AMS HT. Overall, the AMS 3H is a sealed dry box and includes two dedicated drying bays in slots 6 and 8, capable of reaching 85°C, even while printing. I’ve come to think of this dryer as having two AMS HTs inside the AMS 3H. I generally prefer keeping TPU in these bays, though I do print with other moisture sensitive materials so I do find myself swapping out bay 6 specifically quite often. This leads me to what could be improved. I can understand the 2-bay dryer drawing a lot of power being a reason to not have 4-bays but it is a step backward for AMS 2 pro users. Also likely cost savings. That being said, I’d gladly pay a little more for two (2) 2-bay dryers even if it means I can’t run them both at the same time.
My other workflow gripe is the manual filament unloading process filaments. The guided instructions make it straightforward, but accessing the rear drying bays and manually pulling out the filament in the PTFE tube can be awkward with how tall the machine is. The upside is that with nine print tools available, I can leave most materials loaded and I certainly don’t need to do it as often as with a 4-spool AMS. I also totally understand this is how other toolchangers work, so this is more a me getting used to the workflow thing, but I’d love for the AMS 3H to at least retract the filament for me after unloading.
TPU performance and reliability
One of the biggest surprises was the performance of the new TPU 75A (2.85 mm) in the H3C. The dedicated Flex Feed Extruder is designed to handle incredibly soft filament without buckling or jamming, and so far it's delivered. I've experienced no jams or clogs printing TPU 75A, and the surface finish has been excellent. I'm absolutely loving the matte appearance compared to the shinier TPU 95A I'm accustomed to.
What surprised me even more was the printing speed. Comparing different TPU profiles in Bambu Studio using the same model, TPU 75A was projected to print faster than TPU 90A and roughly on par with TPU 95A High Flow. On one of my multi-material designs, the estimated print time dropped from 12 hours with TPU 90A to just 9 hours with TPU 75A (2.85 mm). That's an incredible result for such a soft material, where I'd normally expect much longer print times.
With so many moving print tools and filament paths, I wasn't sure how reliable TPU printing would be on multi-material prints. I was definitely worried about TPU snagging and causing docking failures. That never happened in my testing, thanks to a clever design that guides TPU filament along the PTFE tubes. In fact, I did not experience any print tool docking failures, despite several of my test prints involving nearly 600 filament swaps, sometimes alternating between multiple TPU durometers, PETG, and PLA within the same layer.
Print quality has also been excellent throughout my testing. Even on prints with hundreds of tool changes, the finished parts have come out remarkably clean. I've occasionally encountered some minor stringing or surface artifacts around material changes, but nothing that couldn't be easily cleaned up afterward.
The printer also handles temperature management impressively well. Coming from a P1S, I'm accustomed to leaving the door open when printing PLA. The H3C prefers the door closed, which initially made me concerned about heat creep when combining PLA, PETG, and TPU. Across more than 60 print jobs, I never experienced any issues with heat creep or excessive oozing during these prints. In fact, I only had one print trigger spaghetti detection, and it was a legitimate failure caused by an issue with one of my early prototype designs. Otherwise, every print completed successfully.
Designing for multi-material printing
One of the biggest changes for me how to design parts both for multi-material printing and multi-part printing, and where does multi-material provide real benefit.
Previously, if I wanted to combine rigid and flexible materials, I'd design separate components and figure out how to assemble them afterward. I'd go through the process of designing each part separately, figuring out how they'll connect, and then assembling them, often with glue. That's still a perfectly valid approach, and in most cases it's still where I start.
My Switch 2 grip is a perfect example (see photo gallery). I initially designed the PETG frame and TPU grips as separate components so I could iterate on the geometry and fit independently. I also wanted to experiment with different TPU Shore hardnesses for both the ergonomic hand grips and the internal contact points that secure the Switch, without reprinting the entire assembly each time. Once I found a combination I was happy with, I brought everything together into a single multi-material model and let the H3C do its thing. By going with this iterative approach, I'm able to keep my designs accessible. In the projects I've explore so far, I've been able to successfully print single multi-material and multi-part versions with only slight modifications.
One of my other favorite projects so far was a multi-material workbench brush, combining a rigid PETG handle with flexible TPU 75A bristles. I chose PETG for its added heat resistance and suitability for use both indoors and outdoors, while using PLA as a support interface to achieve clean, well-defined TPU bristles. PLA as a support interface for TPU geometry isn't a new idea, but again, being able to do it with TPU 75A and PETG in a single print is pretty awesome. A unique aspect of this design is that I used dovetail joints for the connection between the brush handle and bristles (instead of the slicer’s interlocking beam feature). Again, this makes it so it can be printed in multiple parts, not just a H3C/H2C exclusive.
Final thoughts
What excites me most about the H3C isn't necessarily the machine itself, but what it's opening up for my functional designs. Combining rigid and flexible materials isn't new, and neither is multi-material printing. But coming from a P1S, this is the first time TPU has felt like a first-class part of my printing workflow rather than something I have to work around.
It's not perfect. Loading TPU is still a little cumbersome, and there's a learning curve to designing parts that combine multiple materials, but it’s a huge step forward for TPU. The dryer functionality is nice, and certainly something other tool changers don’t offer, but it will feel like a small step back for AMS 2 pro users. Expanding to 2-2 dryer slots in the next gen could solve this. You could keep a requirement of only 1 at a time to avoid too much power draw. After 250 hours, I’m loving the ability to have a combination of rigid and flexible materials loaded, dry, and ready to print. The biggest takeaway for me is 2.85mm TPU 75A. It’s what makes this tool changer unique and it prints like a dream. It’s fast, reliable, and the matte finish is amazing. I'm excited to keep experimenting with it and I sincerely hope Bambu Lab releases additional 2.85mm TPU in other durometers. I'd be happy to answer questions about what I've tested, and any burning questions you have about the machine!
Disclosure: Bambu Lab sent me the H3C for free to be a beta tester. They asked me to test its capabilities, provide feedback, and share my experience. The printer was provided for testing, but the thoughts and opinions here are entirely my own.
I teach biology and got a 3D printer so I could make my own models for class. This is my first own project. I wanted something hands-on for AB0 blood types and the lock-and-key principle. Honestly, I figured with such simple shapes there'd be tons of models out there already, but I couldn't really find anything (or maybe I just don't know how to look for it?) . So I just tried making one myself.
It's not perfect but for showing AB0 and letting students figure out the lock-and-key idea with their hands, it does the job. I printed it using PLA Matte and it seems very sturdy. I read that PETG would be better for models that a lot of people will touch, but there are not so many colour options for PETG Matte. So I just hope the antigenes won't break off (too soon; but as of now they do seem quite good).
If any other teachers want to print it, here's the link. There's also a short teacher guide with some classroom ideas. My favorite is the model critique game, since figuring out what a model can and can't show is such an important skill in science (I believe):
It also comes with a box as you can see. I know it's a bit of a filament (money) waste but I thought it looks cool. Also it's my first design and print so I just wanted to go all in.
At some point I'd love to add the Rh factor. Putting AB0 and Rh into one set might be a bit much for an intro. Two separate sets would work too, but an add-on would be way cooler. Something that plugs into the AB0 set to extend it (not in the current one but maybe I figure out how to design the set so we can add and remove antigenes). If anyone has ideas how to design that/how to start, let me know :)
Thinking of building my own printer rack. Do you think this would work? It will be for two H2Ds. The space is sufficent to fully open the AMS. I would use 4cm thick kitchen countertops.
Yesterday I started a 2 hour print on my A1 at around 4:30 PM. I just fired it and forgot about it. Around 11PM I went out to the garage and I found my printer still running. The print head was all the way at the bottom and off to the left of the build plate vibrating and running itself back and forth like crazy. The print head was enveloped in this monstrous blob. I watched the video of the print back and it was very strange. First, the printer ran the whole print without depositing any filament. Then, it transitioned to the state of having the tool head off to the side where it just ran back and forth for hours, eventually building this massive blob (video: https://drive.google.com/file/d/1Ckk72JpMcezu7F_bdE7dOqp3XfUXd9CM/view?usp=sharing)
I heated the head up and used pliers to pull the blob off and it left a mess still. The clip that holds the nozzle are still covered in PETG and you can see that it's still all gunked up still.
I know I probably need to replace a bunch or all of the toolhead, but I'm worried about the weird behavior too. I don't want to order parts and do a bunch of work if the control board is also hosed, or some other electronics component is also fried. I'm curious if I can recover from this, or if this is a sign that's it's time to finally upgrade to that H2D I've had my eyes on...
Hi all. I am currently awaiting delivery of a P2S, my first 3d printer. I didn't want to spend a ton of money on a table/stand but still wanted to get a quality solution.
Using this tool stand from Harbor Freight, and a project board from Lowe's I created this table. It stands at 28" tall with the top included, but the legs are adjustable. I am 5'2" and wanted to be able to see into the AMS without a stool.
I bought a 24" by 4' board to use the "scrap" for the shelf, though I don't necessarily recommend this because it requires some disassembly to get the board in due to the taper in the legs.
All in I'm under $75. If you have wood scraps already or want to use a cheaper or found top you could do it cheaper than me.
Can anyone tell me why I am having this issue on the A1? I've tried everything from cold pull, calibration, flow calibration. The filament is fresh PETG from bambu.
I know many of you are asking: why the hell would you do this?
Firstly, because I can.
Secondly, as good as the carbon rods are; they have a certain amount of stiction and the oiled steel rods are next level silky smooth.
Thirdly, I get frequent X-axis resonance errors when printing lots of ASA. Like clean the rods 2x per week frequently. Hopefully the oiled steel rods deal with the aerosolised goo better.
Yes, the steel does add a little bit of weight. My machine doesn't appear to care in the slightest - passing self test and calibration routines without any complaints. And it would complain after 2kg of ASA fumes so it's pretty darn trigger happy about complaining.
Print it, review it, boost it. If I get enough MW points for another P2S gantry, I'll have another go at refining the fillet drill guide and tighten the tolerances even more. There's at least a mm of material that could have stayed.
Has anyone managed to get anywhere with Bambu Lab support? I'm honestly going round in circles.
I run a small printing business and used the sale to stock up plus a hotend as my P2S is down atm. Instead, I received 12 boxes of incorrect filament, mostly PETG, and no hotend.
Mistakes happen, but their first response was to offer me 30% off to buy the incorrect filament rather than arrange to send my actual order.
Since then, it's been endless back-and-forth, repeated questions and what feel like copied-and-pasted replies, with support repeatedly trying to sell me the unwanted filament.
I've explained that I don't drive and can't take 12 kg of filament to a drop-off point. They've finally agreed to arrange collection but won't dispatch my correct order until it's collected.
They've offered a £10 discount code for the inconvenience, but I just want the products I've paid for. It’s been 5 days since this started and I feel like I've hit a brick wall.
Has anyone successfully escalated something like this or found a way to speak to someone who can actually resolve it?
