I designed this to generate various sizes of stools for around the house... one to support my portable AC about 12 inches off the ground, one for my height-challenged spouse to reach the top shelves in the kitchen, one for getting into the pool, etc.

The example stool size is for making from a single sheet of 24x24 inch wood that is 18.5mm thick but everything is parametric and can be changed.

The file will generate SVG/DXF files for use in a CNC router but you have to download the file and load it on your computer - the online customizer cannot handle 2d file generation.
