The additional versions allow you to print multiples in one go and snap them apart afterwards. This may not work as a shareable file as it is worth watching a youtube video (below) on stacking prints and then printing a simpler model and tweaking the spacing. I found .04mm air gap to be most suitable for myself, though the video suggests slicing would round this number relative to the layer width. https://www.youtube.com/watch?v=MHKBvk8IAc0
