About this model

I made this octagonal pointless passthrough as the smooth, rounded one in my BEST Series. Its fully rounded edges and lack of sharp points make it one of the more child-safe shapes I have made, and the clean geometry prints reliably.

It is a vortex passthrough with separate inner and outer pieces, and the fit between them is what makes it feel smooth.

Print settings

  • Material: PLA, PETG, or ABS/ASA.
  • Infill: 0%.
  • Layer height: 0.2 mm recommended.
  • Perimeters: 2.
  • Top and bottom layers: 4.
  • Print speed: 50 to 60 mm/s.
  • Cooling: 100% fan after initial layers.
  • Supports: none.
  • Brim: none.

Inner piece fit: If the inner and outer pieces are not quite right, the passthrough will not feel as smooth as it should. For the inner piece only, I set XY Size Compensation to -0.35 to improve the fit. I use this setting only because this model has a separate inner passthrough piece, and it replaces the older -0.2 mm value.

Tips

  • Scale up for young children: if I am printing for young children, I scale the model larger than the size of their mouth to avoid any choking hazard.
  • Let the build plate cool: I let the build plate fully cool before removing the vortex, so the parts do not warp.
  • Check the fit: if the inner and outer pieces are not quite right, the passthrough will not feel as smooth as it should.
