About size of flattened sticker and formed sticker

I return to the fact that there must be correspondence between the total length of the flat and folded sticker.
This is important in my opinion because it allows us to do the job only once and, if there is a programmer who assists us, even do it automatically.

I'll start with stickerback 61678b02 because it only has two sides and it's easier to describe the process.
Here the method is objectively excessive, but it is mechanically the same that you can also use for a sticker with a very high curvature and multiple faces such as 6143b01 and 93273b01.

To create the 6177969bc01 sticker you need to fold the flat sticker and fit it to 61678b02. You can do this by projecting the design onto the slanted faces or by splitting the design in two and rotating the resulting two subparts.

The first solution has the following disadvantages:
 you have to design a new sticker, without reusing the flat design already made;
 the resulting sticker is not perfectly flat, especially when you start rounding the vertices;
 you must arbitrarily choose the angle at which to project the initial design;
 if there is any detail on the margin you may lose it with the projection and you have to repeat the operation.

It has the advantage that all the folded sticker is in one file.

The second solution has the following disadvantages:
 it involves a number of subparts equal to the number of faces to be covered; 
 it takes a little foresight if you want to reduce the number of decimal places.

The second solution has the following advantages:
 it can be automated, there is nothing to decide;
 everything that is in the flat design is reported directly in the peigato sticker.
 it can be applied for any folded sticker, any curvature it has and any number of faces it has.

Basically, once you've decided on the flat design and know which piece it's to be applied to, you don't have to worry about how to bend it.

Ok, the procedure:
Step 1: Draw the flat sticker
   
Step 2: Cut the sticker along the fold lines
   
Step 3: Create the two subparts
   
Step 4: Move the origin where it is needed to make the bend. *
       
Step 5: Join and simplify the vertices due to the cut, round the inner points of the design as you like (to as many decimal places as you prefer), except those on the cut line and those on the final edge. (On red lines and inside the red circles).
   
Step 6: Arrange the names in the main parts referring to the two subparts now created and you have the two stickers ready (flat and folded).

Same thing for these two more complicated stickers in terms of number of faces. 6142271i and 6253811ab.
       
           

However, the whole thing works if you keep the total lengths

* This is because the center of rotation is on the bottom face of the stickerback and not on the vertex of the top face.
