You get an industrial staircase in three different designs.
Version 1: only stages
Version 2: steps and stringers
Version 3: steps, stringers and handrail
With the settings of the Geometry Node (modifier) you can set up the number of steps, the height of the handrail and the colors of the individual elements.
The files can be integrated wonderfully as a K-Pack in KitOps.
Simply unzip the ZIP file and place the folder structure in your K-Pack folder.
If you don't want to use Kit Ops, you can find the individual stairs in the corresponding blend file, which was created in Blender version 3.4
KitOps is free and you can download it here:
