inverted face (overlap) at the U

Removed overlaps and flipped faces.

THis is too much
3 15 24.8673 -.25 -.0145 26.6605 -.25 .9019 26.5024 -.25 .8196

This overlaps in the same area
3 15 24.8673 -.25 -.0145 26.8235 -.25 .9739 26.6605 -.25 .9019

Try not to make the triange so thin, i.e. ig you make the triangle from the top of the L instead of the S the Triangles are much better shaped andx easier to spot if something is not good.

ALso the bottom white triangles betwen the U, L, S and A would benefit by beig made from this vertex
0 !LPE VERTEX 26.2 -.25 6.2604

Somehow edger tells me that here is something wrong, but I cannot spot it, Rene?
3 3 -7.7081 -.25 6.828 -5.5182 -.25 6.8237 -5.5182 -.25 6.8499
4 3 -7.7081 -.25 6.828 -8.2681 -.25 6.828 -8.3446 -.25 6.8499 -5.5182 -.25 6.8499

It draws me lines like an overlap, but I cannot see one, I think it is due to the vertex not being exactly on the vertex of the prim, but that a very very small mismatch, that can be ignored

May be join this
0 !LPE VERTEX -5.5182 -.25 6.8237
to
0 !LPE VERTEX -5.5182 -.25 6.8499

That should be it then with this subpart :-)

In case in was not mentioned in the other files/comments for this sticker: Triangle „3 3 -5.5182 -.25 6.8499 -8.2681 -.25 6.828 -8.3446 -.25 6.8499“ is inverted.
