Pretzel Ornament

About this project

A classic twisted pretzel as a flat, hangable ornament. One soft rope loops into the familiar two lobes and crossed arms, with a small rope loop tucked into the notch at the top for a ribbon or hook.

How it's built

  • Rope - the right half is a smooth spline stroked to the rope width; the left half is a mirrored copy, so the pretzel is always symmetric.
  • Loop - a ring of the same rope, placed by formula so it wedges into the notch between the lobes and sinks half a rope-width into both arms, whatever the size, proportions or rope thickness.
  • Body - the ropes and loop are blended where they meet, the hole is cut, and the outline is inflated so the rope has a soft, rounded cross-section.

Parameters

Group Control What it does
Shape Half-width 15-60 mm overall size
Shape Aspect Squat (0.75) to tall (1.3)
Rope Rope radius Rope thickness; capped so the lower holes stay open
Rope Flatness 1 = round rope, lower = flatter
Rope Blend Fillet where the ropes cross
Hanging loop Loop on/off, hole radius Turn the loop off for a plain pretzel

Printing

Print flat on the bed. Because the rope is fully rounded, the bottom edge overhangs a little all round; a brim helps it stay down, or lower the Flatness for a wider foot.
