QR badge

Simple scad to generate STL model of badge with qr code.

I designed it to make simple badge to help people connect to WIFI, but you can use it however you want!

How to create STL with docker-compose

1. Prepare svg file of your desired qr code (or provide parameters for its generation in docker-compose.yaml file)

2. Change all the necessary parameters in the environment section of the docker-compose.yaml file

3. Run docker-compose up

How to create STL with docker (old)

1. Prepare svg file of your desired QR code

2. Put it in the same folder as main.scad and call it qr.svg

3. Change all necessary parameters in main.scad file

4. Build docker image

docker build -t qr_badger .

4. Run given image

docker run --mount type=bind,source="$(pwd)"/,target=/data qr_badger

You can freely pass parameters to change the result of output model. For example:

docker run \
    -e LABEL='New label' \
    -e ADD_RING=false \
    -e QR_SIZE=150 \
    -e SVG_PATH='./qr.svg'
    --mount type=bind,source="$(pwd)"/,target=/data qr_badger

Or generate qr on the fly:

docker run \
    -e LABEL='My WIFI' \
    -e ADD_RING=false \
    -e QR_SIZE=150 \
    -e WIFI_SSID="My WIFI" \
    -e WIFI_PASSWORD="admin1" \
    --mount type=bind,source="$(pwd)"/,target=/data qr_badger

Full list of parameters presented in ./docker-compose.yaml file.
