Hi everyone!

I'm currently working on my very first 3D model - a portable power station designed for four 20Ah cells. The plan is for it to deliver around 256W of output.

I immediately decided against making a simple box because I really enjoy good-looking industrial design, so I came up with this concept instead.

I've never done 3D modeling before. After watching a few YouTube tutorials, this is what I managed to create.

I'd really appreciate any constructive criticism, suggestions, or just your honest opinion. I'm here to learn, so don't hold back!

After making metal sonic i had to try making a Mecha Sonic especially after reading Scrapnik island.

What do you think is needed to make him better?

(I'm still designing the arms and legs)

Been annoyed for ages by the strips of light that come in at the sides of blackout roller blinds. The fabric just hangs next to the wall with nothing holding it flush, so I designed these side guides to fix it.

They press the fabric edge flat against the wall while letting the blind roll up and down completely freely. Went through a few iterations to get the grip tension right but really happy with where they landed.

Print details:

- This version is optimised for 2 nozzle dual extrusion printers.

- A NO AMS single extrusion version is currently in development

- PETG

- Fits most standard outside-mounted roller blinds

Files are live on Thangs now. Launching at $4.99 for the first 24 hours, then going up to $5.99, link in comments.

Happy to answer any questions on settings, sizing or the design process.

What do you think?

This was a fun project. Let me know what you think! The model is available on makerworld: https://makerworld.com/nl/models/3011283

Because the last post got deleted for ai images (yeah I know it wasn’t that smart) also is just a tool get over it, anyway I’m uploading again my free model

https://makerworld.com/en/models/3006039-miniature-suitcase-luggage-tags-nfc-enabled#profileId-3375826

It’s a fun concept, I know that NFC isn’t exactly safe to scan especially in an airport act but is a good use case for that kind of tech, the same logic applies to any QR code (or anything really you scan, copy or click without knowing exactly how it’s working or where it redirects you)

Anyway, a lot of you guys criticize hard my design and the use case and the images that I originally uploaded. I really appreciate the feedback and the concerns about its safety etc, but over all it’s a fun concept project, I’m glad that I made it and share it for free with the community.

Create. Don’t hate.

Love you all, happy printing!

I designed this 3d printable mechanical expanding spinning top and I think it's great fun and wanted to share it!

Hey guys!

I'm often looking for an enclosure for my DIY projects and designing it in FreeCAD always felt like overkill. I don't have time to learn these tools and if I just want to test my idea I don't see any reason to spen a lot of time for creating a simple box, so I built PrintCasing https://printcasing.com. It's a free enclosure generator. No install, no sign-up, just open, start tweaking, and download a ready to print .stl file.

What it does:

• Pick your inner dimensions (width × length × height) and wall thickness
• Add port cutouts on any wall (USB-A, USB-C, HDMI, Ethernet, D-Sub, circular, rectangular or use a custom size)
• Auto-generated PCB standoffs on the base, lid, or any wall, grid mode for standard boards, or list mode for custom hole patterns (Raspberry Pi, Arduino, etc.)
• a flat lid or a self-aligning recessed lip lid that snaps
• Optional corner screw bosses
• Ventilation grills
• Custom text engraving on the lid
• One-click STL export
• Tolerance for lid fit is adjustable per-printer
• runs in the browser

I'd appreciate for any feedback, as it's still buggy and I don't know which features I should add to not make it bloated and still usable

EDIT @ 6:57 PM 06/28: We've done it you beautiful people, we filled the quotas for body braces! THANK YOU everyone who helped! Right now we are pivoting towards Neck Stabilizers and braces for PETS!

Makers, on June 24, at around 6:30 PM, Venezuela was shaken to it’s foundations by 2 long, 7.1 and 7.5 magnitude earthquakes 39 seconds apart which combined lasted over 3 minutes, ending with the earth growling like a lion.

it’s no secret that our government has plundered all our resources and we have almost no infrastructure to deal with this, the current unofficial tally is 63k reported missing, with 50k unaccounted for, but the number could be much higher because we have a lot of rural areas and places without power or communication.

The international community has thankfully sent a lot of aid towards our way, but logistics take time and the government are ACTIVELY hampering efforts for any international help to be effective, while almost everyone on the ground helping being regular civilians.

I’m not going to ask any monetary donations to any one person or foundation, instead, I ask for something only the maker community can do, and that is make things out of thin air.

A company here called Ostec3D gave away their files for 3D printed casts, they are printed using PLA and thermoforged around people’s body by softening it with warm water.

There are a lot of Venezuelans all around the world, for obvious reasons, who have set up aid centers where you can drop them off, if you have spare machines/material or want to help, ALL Venezuelans would appreciate it.

I myself have an H2D and have printed 5 casts already, but I’ve been without power since 10 AM.

Here are the relevant resources.

Like a lot of you, I had hundreds of STL files scattered across drives and folders with no good way to find anything. I kept downloading the same models twice because I forgot I already had them. So I built something to fix it.

My3DLibrary is a free, portable Windows and Mac app that turns your model folders into a clean, browsable library — like Plex, but for your 3D print collection.

Fair warning upfront: this isn't a polished commercial product. It's a hobby project built by one person in their spare time. The UI isn't going to blow you away and there are definitely rough edges. But the whole point of this app is that it's 100% local — your files never leave your PC, there's no account to create, no cloud subscription, no data collection, nothing phoning home. Just a simple tool that runs on your machine and organizes your stuff.

What it does:

• Scans your folders and organizes models into collections with thumbnail previews
• Built-in interactive 3D STL viewer — click any model to spin it around
• Search and filter by name or tag
• Optional AI auto-tagging using Ollama (free, local) or OpenAI — it looks at your thumbnails and suggests tags automatically
• Supports multiple library locations across different drives
• Works with Google Drive for Desktop
• Fully portable — no installer, no admin rights, runs from a USB drive if you want

I've been using it daily and it genuinely solves the problem for me. I'd love for people to try it and tell me what's broken or what features they want next — feedback at this stage is more valuable than anything.
