About this model

This pumpkin passthrough is my festive take on the vortex idea, and it is fun to print and even more fun to use. I like it because it is decorative first, with a clean all-around look that works as a seasonal desk piece or a small gift.

The color choices do a lot of the work here. For a bold contrast, print the pumpkin part in orange and the vortex part in green. Another option is to print most of the inner vortex in orange, then insert a color change near the top and finish with green, which adds depth and visual appeal.

Print settings

  • Pumpkin infill: 10%-75%
  • Vortex infill: 0%-10%
  • Infill type: Gyroid
  • Layer height: 0.2 mm recommended
  • Brim: optional
  • Supports: none

Tips

  • Inner piece fit: set XY Size Compensation to -0.35 mm for the separate inner piece in my slicer, under Print Settings, Advanced, XY Size Compensation. That replaces the older -0.1 mm value and improves fit and tolerances for the inner piece.
  • Smooth PEI sheets: a brim is especially helpful on smooth PEI sheets, and a well-calibrated printer handles it easily.
