Chopper: Partitioning Models into 3D-Printable Parts

(not my paper)

python -m venv venv

pip install -r requirements.txt

go to https://www.lfd.uci.edu/~gohlke/pythonlibs and download the commented out packages from requirements.txt

python main.py

python main.py -c my_config.yml

beam_width: increasing this will cause the process to take longer but will (in theory) make the output better
connector_diameter: side length of the connector pegs (cubes)
connector_spacing: minimum distance between adjacent connectors
connector_tolerance: extra side length for the 'slots'
mesh: file path to stl, can also override this on command line in main.py
part_separation: experimental feature, sometimes helps, sometimes hurts
printer_extents: volume of your cartesian printer (currently do not support delta-style printers)
directory: directory where the output stls, config file, and save progress will be stored a new directory will be created within this directory with the 'name' and the datetime string
name: name of job, this will influence what the name of the output directory is
plane_spacing: how many planes to consider for each normal, increasing this will cause the process to take longer but will possibly make the output better

See bunny_config.yml or shoerack_config.yml for examples
