Sticker bottoms - Subfile or Primitive

[Willy Tschager]

Let's go with something very simple like "sticker-back-[partnumber]-[a-z].dat"
I don't think many parts will have a need for many backside shapes. Maybe [01-10] is enough, instead of [a-z]?

Or a simple suffix? Maybe [partnumber][b01-b09,b0a-b0z] where "b" stands for "back side"?

I see no reason having a full description of different details in the filename.  That belongs in the description of the subpart.

So you would have to check the size of the an old part to see if that back suits your new sticker??? I've got that sticker for a Tile 2x2. Go aheay an tell me the right part number for my sticker.

The filename should tell you right away if this is the right back for your 1.9 x 1.9 sticker. If you wanna simply safe on the radius, as I presume that all 1.9 x 1.9 stickers for a Tile 2x2 come with the same radius. "sticker-back-1,9x1,9-rounded-corners.dat"
