I decided to share those totally crude and mostly innacurate models I used in previous picture.

I advice using those objects in flat mode, not smooth mode.



grab OBJ models Here

If someone doesn't know how to remove blue lines in blender edit mode, click here

If site's gonna go down, I'll quote the solution:

"Those are edges marked as “Sharp”. They’re used with smooth shading to designate shading seams.

If you want to get rid of it, select all, Mesh -> Edges -> Clear Sharp."

Please let me know what you think.
Also let me know, if those models were helpful for any of you.
