Converting Mesh to Solid

[Arsoy]

I can't share original files, but the above folder has the files I've created (numbered in order of creation). I was given a mesh, which I converted to STL, which was then used to create everything else.speed test vidmate 123movies

What above folder?

Does your solution resolve the creation of non-manifold surfaces and related non-printable characteristics of the original?

According to my experience, maybe it is impossible to do that on this model.
For some simple models, it is ok to convert from mesh to solid ;
For complex models, it is too hard to do that.Even though you can do that,many details will be lost.
The best way is to recreate the 3d models,but it needs a lot of time.
And another way is to modify the STL file directly,of course the final file will be STL format too-but usually this is the only way.
