About this model

This reverse twist set winds opposite from the rest of the series, and that backwards feel is the point. The three passthroughs are fully compatible with each other, so I can print them in colors I like and use them as a set.

My favorite is the triangle passthrough. It is especially addictive, with a unique geometry that feels different from the others. I printed the set in black PLA and royal blue PLA.

Print settings

  • Infill: 35% to 40%
  • Infill type: Adaptive cubic
  • Perimeters: 2
  • Layer height: 0.2 mm
  • Top and bottom layers: 4
  • Print speed: 50 to 60 mm/s
  • Fan: 100% after the initial layers
  • Brim: none
  • Supports: none
  • Raft: none
  • Filament: PLA or PETG

Tips

  • Inner piece clearance: For clearance, set the inner-piece XY Size Compensation to -0.35. In my slicer, this is the XY Contour Compensation or Horizontal Expansion setting. This is already applied to the files, so I just use the slicer as provided unless clearance issues come up.
  • Handle the triangle piece gently: Its edges are weaker, so I avoid rough use with that one.
