tool_trace

Take pictures of your tools and create an outline in svg.

For this to work, you will need to make sure that you take quality pictures with adequate lighting from a consistent distance.

I use this phone stand and a light panel

Calibration

The distance between the camera and tool may vary from person to person. To adjust for this variance there is a simple calibration process:

1. Take a picture of a 10mm x 10mm square
2. Run the calibrate command and follow the prompts
3. As long as you never change the following you should never have to calibrate again:

• distance between tool and camera
• camera/phone

python3 tool_trace.py calibrate  /path/to/square.jpg

Adjusted image contrast of square.jpg
Smoothing/reducing contour points
Writing SVG to: images/svg/square-unscaled.svg
Start a new fusion sketch and import images/svg/square-unscaled.svg
Using the Inspect > Measure tool, measure the length of one of the sides of the square
Enter your value: 38.2
149.41903686523438 pixels in this program is 38.2 mm in fusion
Our contours should be scaled down by 0.2617801047120419%
Updating scaling factor to 0.2617801047120419 in config.yaml
Producing fusion scale svg
Writing SVG to: images/svg/square-scaled.svg

Convert Image to SVG

1. Take a picture of the tool
2. Run the convert command
3. Import resulting svg file into Fusion 360 (or whatever you use)

python3 tool_trace.py convert images/src/micro-cutters.jpg
Adjusted image contrast of images/src/micro-cutters.jpg
Extracted contours from image
Smoothing/reducing contour points
Rotating contour by: -1.6011782884597778
Generated dugout
Writing SVG to: images/svg/micro-cutters.svg

I don't any of the extra generated stuff (dugouts)

python3 tool_trace.py convert  images/src/micro-cutters.jpg --no-dugout

Example workflow

1. Take picture of tool in phone stand
2. Share photo to host computer via AirDrop
3. Run ./grab_last_image_upload.sh to retrieve the last image downloaded
4. Give the tool a name
5. Convert to svg
6. Create new Fusion 360 Design
7. Generate a gridfinity bin using this generator
8. Import svg onto the face of the bin
9. Offset the tool contour by 1.5mm
10. Extrude dugout and tool contour into bin
11. 3D Print
