Simple python script for converting gerber files into a 3d printable solder stencil scad file
gerber to scad requires python3.9
- Make sure you have (poetry)[https://python-poetry.org/docs/] installed
- Run poetry install
Note: on M1 macs, scipy doesn't install correctly out of the box. If you're getting installation errors, try this:
brew install openblas
export OPENBLAS="$(brew --prefix openblas)"
poetry install- To activate the poetry virtualenv, run
poetry shell.
You should now be able to run the script. You'll get some information on available options if you run it with the -h argument:
(env) $ python main.py -h
usage: main.py [-h] [-t THICKNESS] [-n] [-L LEDGE_HEIGHT] [-g GAP]
[-i INCREASE_HOLE_SIZE]
outline_file solderpaste_file output_file
Convert gerber files to an scad 3d printable solder stencil.
positional arguments:
outline_file Outline file
solderpaste_file Solderpaste file
output_file Output file
optional arguments:
-h, --help show this help message and exit
-t THICKNESS, --thickness THICKNESS
Thickness (in mm) of the stencil. Make sure this is a
multiple of the layer height you use for printing
(default: 0.2)
-n, --no-ledge By default, a ledge around half the outline of the
board is included, to allow aligning the stencil
easily. Pass this to exclude this ledge.
-L LEDGE_HEIGHT, --ledge-height LEDGE_HEIGHT
Height of the stencil ledge. This should be less than
the thickness of the PCB (default: 1.2)
-g GAP, --gap GAP Gap (in mm) between board and stencil ledge. Increase
this if the fit of the stencil is too tight (default:
0.0)
-i INCREASE_HOLE_SIZE, --increase-hole-size INCREASE_HOLE_SIZE
Increase the size of all holes in the stencil by this
amount (in mm). Use this if you find holes get printed
smaller than they should (default: 0.0)For basic usage, simply run the script with input files for the gerber outline and solderpaste files and specify an output:
python main.py outline_file.gko toppaste_file.gtp output.scad
