Tutorial 4: Crystal Ring

Create a ring of faceted towers: a small Polygon is offset with Move, then Array Polar copies it around the bed centre, and Layer Stacker adds height, twist, and taper—like a parametric candelabra base.

What you'll learn

Polygon for a compact footprint
Move to shift geometry before instancing
Array Polar with pivot driven by Print Bed center
Layer Stacker rotationPerLayerDeg and end scale

Prerequisites

Tutorials 1–3 or comfort with path → toolpath chains

Step 1: Offsets and polar array

Move and Array Polar

Array Polar repeats geometry (path / mesh / toolpath) about pivot on axis— here Z through the bed origin.

Step 1

Bed → polygon → move → array

Connect Print Bed center to Polygon center. On Move, set offset to push the small polygon outward (e.g. 20, 0, 0). Wire Polygon path → Move geometry. Set Array Polar Count to 8, Total ° to 360, Axis to Z, and wire Print Bed center → pivot.

Step 2: Stack to toolpath

Step 2

Layer Stacker to Output

Connect Array Polar path to Layer Stacker path. Set Layer H, Layers, Rotation °/layer, and Taper (end scale). Wire Layer Stacker toolpath → Output Toolpath.

Outcome

A radial print with a clear seam strategy from stacked layers and optional twist.
