About this model

This rectangle passthrough is the straight-edged take on my BEST passthrough series, and its sharp corners make the twist look completely different from the round versions. I like it best in two colors from opposite ends of the color spectrum, since the contrast really brings out the geometry.

Print settings

  • Infill: 0-10%
  • Filament: PLA
  • Supports: not required
  • Brim: not needed
  • Inner piece XY Size Compensation: −0.35 mm (sometimes called Horizontal Expansion), for a smoother fit

Tips

  • Fit: the shape is the draw, but the fit is the thing to get right. If the inner piece 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.

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