Here are four printed metal parts (not six!) and nine tungsten carbide bearings holding them together/apart. Yes, there should be 12 bearings...but there aren't.
Although it is a pure snap-fit, without adhesive or other cheating, I wouldn't class Holly as a puzzle, as it's rather difficult to get together, and once together, a very robust assembly.
