The files that start with a letter are meant to be grouped and printed with a multimedia printer. The others can be printed on a regular printer and you can change colors between layers for the butterfly wing and flowers if you want the same effect as using a mm.
There isn't much to slicing them but I think I used 100% infill just to get them as sturdy as possible.
