Painter's Caltrops or Stands
thingiverse
I've stumbled upon several Painter Stands on this website, but unfortunately, none of them offered simple print settings. To demonstrate the interlocking mechanism, I recommend printing two identical shapes and combining them in a way that their points align perfectly, regardless of how you lay them down. Using PLA material with 50% infill and four outline layers produced decent results.
