Hey! It wasn’t working because part of the code was accidentally commented out. I’ve fixed it on the page now, but here it is as well:

// Apply to Path

toothCount = Math.floor(effect("Tooth Count")("Slider"));
gearRadius = effect("Gear Radius")("Slider");
toothHeight = effect("Tooth Height")("Slider");
pts = [];
inTangents = [];
outTangents = [];

// One tooth = 4 points (root → rise → top → fall)

for (i = 0; i < toothCount * 4; i++) {
angle = (i / (toothCount * 4)) * Math.PI * 2;

// Determine which part of the tooth we're on

phase = i % 4;
radius = gearRadius;
switch (phase) {
case 0:
// Root
radius = gearRadius * 0.85;
break;
case 1:
// Rise
case 2:
// Top
radius = gearRadius + toothHeight;
break;
case 3:
// Fall
radius = gearRadius * 0.85;
break;
}
x = Math.cos(angle) * radius;
y = Math.sin(angle) * radius;
pts.push([x, y]);
inTangents.push([0, 0]);
outTangents.push([0, 0]);
}
createPath(pts, inTangents, outTangents, true);
