The latest version doesn't have the bolt head exposed; it uses the lowest 10 mm of the totem pole.
3d model print parameters
Looking at the photos, you quickly realise ...that the labyrinth looks much nicer, and that is correct. The totem is printed with a .190mm resolution, and the labyrinth with .090mm.... I just didn't have the patience... ;) I only used supports for things with an angle to horizontal of less than 20 degrees. A postscript: today I printed it with support for everything over 45 degree overhang, and that actually made a noticeable difference in the surface quality at 0.190 mm. I am tempted to do a run at 0.090 mm, even though it takes forever... View the cover photo in full size to see what I'm talking about.
