proposal for easier glueing #86

Hi, I really like your paper model exporter and have built several models in the past. Often I found it is very handy to have tabs on both sides of the seam, especially for concave edges. This way it is possible to use sewing clips (aka "craft clips", "wonder clips") for seams deep inside the model. It would be great to have an option to get tabs on both sides, perhaps for edges above a threshold value.

Right now it is possible to force this by extruding the concave edge to the inside (yes, 3 faces connected) and scale it down a bit to get tabs on both sides. Now the concave edge is somehow split into 2 convex edges, which can conveniently be scratched with a knife from the printed side to get a nice straight edge. (you won't get any index numbers)

Here is a simple model with 2 concave edges to illustrate my proposal:

The approach I recommend is to complete a basic box and stick other shapes onto it.

I believe this is the classical approach of paper modeling, and the script is prepared for this. Edges with 3 connected faces are handled correctly, and you can mark them with Freestyle mark to get a precise mark on the target side.
