Here's a way, I think it's fairly robust.. the steps in the GN group are:

  • Stash face normals
  • Extrude the mesh once
  • Duplicate the extrusion (Stashing dupe indices) and move duplicates out along stashed face-normal by a multiple of dupe index
  • Merge all by distance
  • Scale 'Top' faces (including internal) by a multiple of (shifted) dupe index.
  • Delete all extrusion 'Tops' except the last, to get shot of internal faces

enter image description here

Current inputs:

  • Extrusion height
  • Number of divisions
  • Tip scale
