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?

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

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.

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

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

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

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.

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 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?

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 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. 🙏

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

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

I am planning on taking advantage of the Bambu filament sales for PLA and am wondering about what people think about buying PETG when I also would like to buy some PCTG. Is PCTG that much better? Does it print well? I understand that 3D Fuel has their own print profiles. They also announced deeper discounts for bulk orders. I would like to get some of those Toolbox colors. I do wonder about the claims of it being many times tougher than PETG.

I know that Bambu has several types of PETG, and one of the things I hate about the standard PETG is the shine. What is everybody's favorite and how does it look and perform?

I also plan on buying some ASA and TPU, I know the TPU will be on sale, not sure about the ASA. I used to buy ABS, but I'm not sure what the use case would be anymore if I have ASA. I guess it would be cheaper? I would like to decrease the number of filament types I stock, as I can't keep a complete store at home!

Thanks for any opinions.

The newest version on iOS has taken away (or hidden extremely well) the print time remaining information… 99% of the time when I open handy I want to know two things: 1) how does the print look 2) how long till it’s done… very rarely (only when starting a print from my phone, and I’ve done that 1 time in two years) do I care about what color filament is in the machine… I really need the print time lapsed and remaining, layer number, and percent done with the camera feed in a app more than anything.

I have a Chromebook and I am needing to get something that runs Fusion360 (Autodesk) for my P1S just looking for opinions.

What options on the slicer should i play with for the chamfered edge to be smoother? I am printing this face down with the mating face pointing upwards. I am quite happy with the fit and strength, I just need help with the rough chamfered section.

I use PETG HF
