About this model

This circle passthrough is part of my BEST Impossible Vortex Passthrough series, and it is one of my personal favorites. It runs smoothly and uses minimal filament, which is a big part of why I keep coming back to it.

The fun part is simple: toss the assembled model into the air and catch both pieces as they separate mid-flight. It is the kind of trick that makes people ask how it works.

Print settings

  • Infill: 0% (the model is fully self-supporting)
  • Filament: PLA recommended
  • Supports: not required
  • Brim: not needed
  • Inner piece XY Size Compensation: −0.35 mm (sometimes called Horizontal Expansion), for a smoother fit between the vortex pieces

Tips

  • Fit: the one thing to watch is the fit between the two pieces. If it feels tight, try the tolerance tip below before reprinting at a different scale.
  • A note on XY Size Compensation: for the inner piece only, I set it to −0.35 mm, because this model has a separate inner passthrough piece and the setting gives a smoother fit between the vortex pieces.

My Patreon page is still available at patreon.com/MasterPrinter, but I do not actively update it anymore.
