Cosplay

This is the design repository for NorCal Hakkero Factory No. 1, where we use parametric CAD to make cosplay props. We design cosplay props based on an engineering point of view.

NorCal Hakkero Factory № 1

Most cosplay schematics are created with Blender, CadQuery, and Inkscape.

Development

Install uv, and then execute

uv sync

To get a development environment, run

uv venv

Then, either follow the instruction to activate this venv, or install direnv and create the file

# .envrc
source .venv/bin/activate

Test the environment with python3 -c "import nhf"

To visualize an object, create a file visualize.py, and run cq-editor:

python3 -m cq_editor visualize.py

Folder Structure

• nhf/parts/: Ready-made parts
• nhf/$WORK/$CHARACTER: Design for an individual character

For each individual character, the __init__.py script stores the overall build entry point and the entry point for all unit tests.

Testing

Run all tests with

unittest-parallel
