I can easily see where the problems are in the stl.  The ones that have the non-manifold problems aren’t really needed as there are many other similar stls out there that will print without any problems.  It’s not worth my time to try to fix one.  Thanks for all the good information.

    Yes, Cura 4.6 opens the file and gives the "Your Model is not manifold" error, but the print seems to come out fine.

    Probably because the error is in some place not visible or because it is a very small problem.


    In the course of researching this issue, I came across a free online service (Jomatik) that corrects these Holes and other issues with 3D files making them ready for 3D Printing.


    Check the following link.

    Just drag and drop your file there and it instantly repairs it. Well.... atleast it did mine. 🙂

    The file now loads up in Cura without any errors.



    Hi all, thanks Ashton20001 for the hint, I got spaceship models generated from DoGA CGA, which were non-manifold, and on the 2 exemples I tested, Jomatik solved the issue and the models imported OK into Cura 4.6.2. Now I got to print and see if it's OK.

    There are many tools out there to repair STL files.  Dozens.  Maybe 100 tools.  Even Cura has a plugin for some limited repairs.  I've heard good things about this one:
