About this model

I made this square pyramid vortex passthrough as part of my BEST Impossible Vortex series, and it is one of my personal favorites. It is highly functional while keeping filament use minimal, so it is a cost-effective print that still feels satisfying in the hand.

The best part is how easy it is to print. There are no overhangs and no need for supports or brims, and the geometry stays clean with smooth motion between the parts.

Print settings

  • Infill: 0% (the model is fully self-supporting)
  • Perimeters: 3
  • Layer height: 0.2 mm
  • Wall loops: 2-3
  • Top/Bottom layers: 4-5
  • Filament: PLA recommended (PETG also works well for added durability)
  • Supports: none
  • Brim/Raft: none
  • Print speed: 45-60 mm/s
  • Cooling: part cooling on for PLA, moderate cooling for PETG

Tips

  • Fit: The parts need the right tolerances to move smoothly, so if your printer's precision is off, the fit can feel tight or loose. That is why the XY setting below matters, and why wall loops run 2-3 depending on your printer's precision.
  • Inner piece XY Size Compensation: For the inner piece, I set XY Size Compensation to -0.35. That replaces the older value of -0.2 on this model's page, and it helps ensure a smoother fit and cleaner movement between parts.
