tool to make an stl from 2D image?

Hello friends,

my local fifth graders are doing a series of science lessons which uses this mythical artifact as a focus. The class teacher thought it would be neat to try and 3D print the artifact and let the kids actually handle it vs the print version they are working with now.

The teacher got about this far before hitting issues that prevented printing. I have done a bit of 3-D printing on my ender so I gave it a try but I wasn't able to get even as far as the teacher did by the look of it.

Is anyone aware of any foss tools that might facilitate this or have time to help get us to a printable .stl from these 2d views? TIA!

Wait the teacher got to the point they have a 3d file right?

If so this seems like a job for Blender.

  I should probably ask him again why it wouldn't print he told me on the phone but i have the memory of a goldfish all I know is it ultimately wasn't printable

    I would just about bet Meshy AI gave a “non-manifold” model. 3-D models that are intended to be digital assets can have that issue, and I would suspect it’s easier for an AI to produce them versus properly manifold objects ready to be made solid.
    
    There are ways to fix them though, and Meshy even has their own suggestions (Blender and Meshlab).

Do you know the Nebra Sky Disk? This one has a nice science trail. The book about it is awesome. en.m.wikipedia.org/wiki/Nebra_sky_disc

  no I did not, I have never heard of sky discs I assumed the artifact was just something the teacher made up. I sent them the link to this post so they will probably see this thank you for sharing!

    Hete is the book about the entire story. Well written by a journalist and a scientist. This Sky Disc rewrote many assumptions of the bronze age in Europa.
    
    E.g. Still they don’t know how they could figure out the stars as it is too cloudy in Europe for those observations. They assume a very ancient trade connection to the Middle East where those star images where known already. And some of the gold for the star decorations where from England and Turkey (if I remember correctly) Worth a read :)

I swear a long time ago I did something like this using the microsoft 3d viewer or something. Some microsoft 3d modeling thing

  Microsoft 3D Builder. The most useful software MS has made in the past 15 years. But of course they killed it. You can still find its installer to download from 3rd parties. Its one of the tools I sometimes need and spin up a windows VM for.

If you are starting with nothing then maybe a lithophane conversion on the photo

3dp.rocks/lithophane/ itslitho.com github.com/muldjord/lithomaker

Just some options. 3dp.rocks works well from my experience. That would at least give you a starting point. I’d see if there is some way you can scale it on the z axis of the features are point straight up to get more depth on what the lithophane provides.

    Another option might be Bambu Labs lithophane tool on their site. I haven’t used it but I have used the Keychain maker to make dozens of STLs from 2D images/logos and it works great.

I know there is a workflow template for ComfyUI that has a model that can convert 2d images, or multiple perspectives from photos, into a 3d model

This takes an images and makes an STL. There are others out there like BackflipAI that does some “intelligent” destermination when converting a flat image to 3D.

The Smithsonian has a bunch of scanned STL files of things. 3d.si.edu
