# Images

Project photos and reference photos for the parts on the
[Parts to buy](Parts-to-buy) page.
One folder per part. Component images come from manufacturer/vendor photography, a freely licensed
source, or a file already in this project, and are for builder identification only.

SparkFun and Adafruit images are used here so a builder can recognize the part when it arrives —
not redistributed as marketing material. Those vendor photos stay under their owners' terms. Link
to the product page for authoritative specs.

## Notes

- Originals in `BuildYourOwn/images/` and `BuildYourOwn/cad/encloser/` are left in place.
- If a part is substituted, replace the photo here and update the Parts to buy page.
- No photo is stored here for the GL45 two-port cap or the tube that connects to that cap. Those print files are not in the repository. The GL45 bottle photo is an example of the recommended sample container, not one of those printed parts.
