Hello friends,

my local fifth graders are doing a series of astronomy 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? It’s not supposed to be very thick just a sort of broken disc thingy. TIA!

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

    edit: I sent them an email asking for the .stl they made thanks for the good idea

      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).

        Definitely agree, it probably was a non-manifold mesh. There are several ways to fix this, but one of the easiest is to load it up in Blender, apply a voxel remesh modifier to it, and then re-export.

          When I load a non manifold mesh into my slicer I get “error, click repair” a windows dll starts that repairs the mesh. It’s weird that Windows does this instead of the slicer but I’ve never taken the time to investigate because I’m busy on the next print.
