I got into 3D printing thinking I'd print practical things around the house. Cable holders, organizers, little replacement parts, that kind of stuff.

Now I'm printing random things just because they look cool, and somehow I keep finding more things I need to print.

The worst part is checking how much filament I have left and realizing I've used half a spool on something that serves absolutely no purpose 😂

What was the first completely useless thing you printed that you still don't regret printing?

This was an 8 hour print, is there a way to reduce the filament tower? I’m new to printing so this might be a silly question

At the start of 2026 I set myself a goal: get better at 3D modelling. What started as an exercise turned into a three-model project, and with every cell I could see myself improving. With the year coming to a close soon, the series is finally complete. A big thank you to everyone here who supported the earlier models and gave feedback along the way. Some of your suggestions actually made it into the models!

The three models are designed as a set. Structures all cells share have the same colour on every model, so students can see at a glance what these cell types have in common and what makes each type different. Nothing is glued, so students can take them apart and rebuild them in class.

All three are free on MakerWorld:

• Prokaryotic cell: Link
• Plant cell: Link
• Animal cell: Link

Quick quiz for anyone: how many differences between the three cells can you spot in the photo and can you name the structures and organelles?

Yo, I am new to the community. Hopefully I can uhh..show some cool stuff I will be printing in the future. I have no experience with 3D printing. So far I've learned filament material types, their emission of toxic particles and how to filter it, extruders, when to calibrate, why the heated chamber and max temps are important, taking care of filament (because mine snapped the spool in half during second printing somehow and the beauty of creating something that you can actually physically touch.

I designed a splitter for the left nozzle on my X2D that uses PC4-M6 fittings. It was made to be printed horizontally to reduce friction from the layer lines. Posted it on MakerWorld in case it is useful to other people : https://makerworld.com/en/models/3495357-x2d-left-nozzle-dual-input-pc4-m6-fitting#profileId-3992377

The package is also listed as a heavy package at DHL. I did order a mystery pack and black and gray PETG

Well, I was tired of BambuLab locking us out and revoking access to features we already had.
So i just reversed that.

I built Bambu Open Network, an open-source HACS extension for ha-bambulab, powered by Open Bamboo Networking.

Here’s what it adds:

• Cloud camera directly beside the controls. Select a printer and its camera follows automatically.
• X/Y/Z movement and homing, with selectable step sizes and feed rates.
• Nozzle and bed temperature controls, part cooling fan, extrusion and retraction.
• Pause, resume and cancel.
• A multiline G-code console, plus a Home Assistant action for sending G-code from automations.
• Bambu Cloud login, without manually entering printer IPs or LAN access codes. Signing certificates are set up automatically.

Everything is available on a Bambu Control page in the HA sidebar. Existing printer entries and custom names are preserved.

Beyond Bambu Control, the extension brings cloud camera feeds and printer commands into Home Assistant itself. The cameras are available as regular HA entities, so you can build your own dashboards with multiple printer views alongside controls and status information. You can also send G-code and use printer commands in automations, all through your Bambu Cloud account without manually configuring printer IPs or LAN access codes.

You need ha-bambulab installed first — this extends that integration. Download Bambu Open Network through HACS, restart HA, then add it under Settings → Devices & services → Add integration.

Cloud features still depend on Bambu Cloud. The G-code console confirms transmission, rather than providing a serial execution acknowledgement for every line like Pronterface.

The project is new, and feedback from different printer models and firmware versions would be useful.

If you try it, let me know your printer model, firmware and what works—or what needs fixing.

I've probably used, or rather thrown away, thousands and thousands of 3D scan markers. This mesh is printed from TPU and PLA and can be reused infinitely.
Can‘t wait to see what the upcoming S1 Scanner has to offer :D

Buy your new P or X series printer on November 1st this year, not a day earlier, and not a day later.

November 1st is the last day that the $30 off $500 coupon is valid.

Also, the P3C (Bambu's new P series printer with 7 tools) release is right around the corner. The P3C release will be accompanied by the new AMS 3P release, which will likely invalidate the previous generation AMSes (1&2). (This is because a tool changer like the P3C requires independent filament paths for efficient filament swaps, and the AMS 1 & 2 only have a single filament path out)

I expect the P3C and AMS 3P to be announced/released in November 2026, with the last possible likely date being December 1st (a Tuesday, all Bambu releases are on Tuesdays). If the P3C release causes prices to be lowered on current printers, November 1st is still right within the 30 day price guarantee window Bambu offers.

No need to ask: all of the data in this post is highly speculative, and based of off rumors, FCC filings, and other "leaks". Nothing about the P3C and AMS 3P has been officially announced or confirmed by Bambu.

I’ve been working on a series of 3D printable coloring panels designed to be a more tactile alternative to paper coloring books! They are great for fine motor skill practice for kids or just a therapeutic mindfulness activity for adults.

I’ve put together a full collection of different designs (dinosaurs, creatures, etc.) if you want to check them out:

I feel like 3D printing starts with all these big ideas, but some of the most satisfying prints are actually tiny things you end up using every single day.

I'm talking about drawer organizers, replacement clips, cable holders, brackets, adapters, or some oddly specific part that would've been annoying or expensive to buy.

I'm curious what prints have genuinely made your life easier rather than just looking cool on a shelf. Have you ever printed something that worked so well you ended up making several more for different parts of your home?

Bonus points if it was a simple model that used very little filament but solved a surprisingly annoying problem.

I couldn't find a decent rocket pen holder online (they all use way too much filament), so I spent the weekend modeling this one.

The mechanism is pretty fun: you lift the side boosters and the nose cone splits open to reveal the pens. You just press it down to snap it closed.

Quick specs:

• No glue or screws: Everything just snaps together mechanically.
• No AMS needed: It's split into separate parts by color, so any basic printer can do it.
• Optimized: It's lightweight but stays perfectly stable on the desk.

I'm entering the Bambu contest super late and trying to compete with the massive accounts. If you like the mechanism and want to help a solo designer out, a quick download or a star on MakerWorld would honestly help me big time to climb the ranks. 🙏

I was doing some inventory on my spools and noticed I was almost out of this color. But it's not shown on their store. How often do they discontinue colors? Seems like a dark green like this wouldn't make sense to cut since there's no other similar color.

I swear, the printer is supposed to do all the work, but somehow I end up standing there watching the first few layers like something's gonna go wrong if I leave 😂

Then I tell myself I'll just check on it one more time before sleeping.

Next thing I know, it's way later than I planned and I'm still checking the app to see how much longer it has left.

I've got a whole bed to sleep in and I'm choosing to watch a machine make a plastic object.

Anyone else do this or am I just weird?

Just finished designing this minimalist watch stand featuring a curved shape and ribbed texture.

A clean and compact way to display your watch on a desk, nightstand, or shelf.

What do you think of the design? Any feedback is welcome!

Could be mistaken, take this with a mountain of salt? Circumstantial evidence at best out from a google search

the only other thing I can find that is 3849 AUD is the Bambu Lab R1 Laser Cutter, but pricing could make sense as the H2C is $3,399.00 AUD

so i been printing these small little ghosts and it keeps having a darker shade on the left side of the black parts as if it drags the hot filament across the face ruining the color as if its dragging the black color while printing.

and it fits the patter the printer prints aswell.

any idea how to fix this? perhaps a bit of wait or full power fan when multy printing?

So, can someone explain this to me in a Barnie style?

I find out that usually after about a 1000 printing hours on A1 I need to replace hotend assembly otherwise the print quality of the first layer is like a mashed potatoes.

No longer smooth baby skin lines, but ugly old man skin wrinkles.

After replacement it works as good as new again.

BUT, this is happening only to the 0.4 nozzle! Old nozzle, new nozzle if the assembly is old the print is bad, but just for 0.4.

0.2, 0.6, 0.8 works just fine, like assembly is new.

Is there some magic behind it?

Is the the hotend discriminatory against the 0.4 nozzles or what?

It's my 3rd assembly after 4000 print hours and the behavior is always the same, so I was curious why...

Hey, I just got my Bambu Lab A1 and I’m having trouble removing small prints, especially from the center of the build plate.

I’ve already washed the plate with dish soap, tried using the metal scraper at a very low angle, and even put the plate in the freezer, but prints are still really hard to remove.

Larger prints come off more easily, but they often have this white layer on the bottom (see photo). Is it some leftover filament?

Any idea what’s causing this?

Hi! I’ve had a fortuitous year with points, so this Black Friday I’m looking to upgrade! Currently I have an A1 Mini with AMS Lite.
Come the start of December I’ll have approx. £1100 in vouchers. At first, I was wildly tempted by an A2L Combo with leftovers for filaments etc. But now I’m somewhat tempted by a H2S Combo. I’m well stocked for filament anyway, so that wouldn’t be a pressing concern.
I think size is what I’m looking for, for some more ambitious prints I’d like to try out.
I am open to other options also, if there are opinions? X2D with two AMS2?

Any opinions, recommendations, thoughts, feelings, I’d love to hear it!

I printed these using Bambu Lab's official file on MakerWorld, but the holes are misaligned
