I needed to calculate the measurements for a christmas tree, so I've created a parametric model of it.
The picture contains a tiny print of it 19mm total height.
Ideas came from pages like https://www.charlestoncrafted.com/diy-2x4-wood-christmas-tree/ or this youtube video:
The openscad model is parametric, thus you can change the width of the wood and the height of each step.
The author marked this model as their own original creation.
