Moved to Codeberg

Notice: This project has moved to Codeberg.org. All further development will take place there.

Action Shot

This Python app allows you to generate .scad and .stl files for key tester frames, supporting arbitrary m x n sizes.

In the files/ directory, example output files for 1x1, 2x2, 3x3, and 4x4 sizes are included.

Prerequisites

You can install prerequisites with pip:

pip install -r requirements.txt

This will install the following Python packages:

Usage

You can generate other sizes using the src/generate.py script; example:

src/generate.py 3 5 --output ~/key-tester-3x5.scad

Once you have generated a .scad file, you can use OpenSCAD to generate a .stl file from it:

openscad -o ~/key-tester-3x5.stl ~/key-tester-3x5.scad
