Parametric Spiral Staircase Generator

source

Description:

A fully procedural spiral staircase model generated using CadQuery. This script automates the creation of a classic helical stair structure, featuring a central support column and radially arranged treads. The geometry is optimized for 3D printing and architectural visualization, ensuring a seamless connection between the steps and the central axis.

Key Features:

1. Fully Parametric Design: Easily adjust the total height, radius, and number of steps by modifying simple variables in the script.
2. Automated Step Rotation: The algorithm automatically calculates the necessary rotation angle for each tread based on the step count to ensure a full or partial turn.
3. Integrated Central Column: Steps are fused to a central pole, creating a sturdy, single-piece solid suitable for FDM/SLA printing.
4. Clean Topology: Constructed using solid geometry primitives for error-free export to STEP and STL formats.

Dimensions (Default):

Total Height: 40

Step Width: 8

Step Thickness: 2.5

Central Pole Diameter: 4
