I have seen this in Thingiverse but it is far too large for TinkerCad to accept. It is saying to mesh it and try again. What the heck is mesh, haven't got the faintest on that at all and can Flashprint or TinkerCad do it.
Rod,
ALL 3d print files are composed of thousands of tiny triangles that join together to form various apparently curved shapes. The triangles are so small that neither the printer nor the human eye can normally see them and they interpret them as a true curve.This is called a mesh.
The message you got tells you that the number of triangles is too big for the program to handle and suggests reducing the number of triangles. This is akin to changing the resolution on a standard document printer from say 600dpi to 60dpi - You get an approximation of the original file but with a lot less detail. I don't know for sure but I'd doubt that Flashprint can change the mesh size and you said yourself that Tinkercad can't import it to begin with. You probably need Meshmixer or a similar program. When you get Meshmixer to work please let me know, because it's beyond me!
These two pictures show the mesh effect: The first one is screenshot of the stl of a small figure (67mm high) in Flashprint. I then imported that stl into Sketchup, which took about an hour, and the second picture is a screenshot of the same figure in SU and shows the mesh. The blackish areas are where the triangles are so small and close together that the screen can't separate the lines.
