I would check out Trilium. It’s a general purpose note taking/knowledge base application but it’s very powerful in how it can be used. You could create a note for each item and attach a photo to the note. Then you can add details and have them searchable.
- Open source and has Linux client
- Stores data locally and/or syncs to a server
- Not sure what Nextcloud is but it is easy to self host
- Does not have Android app but it if you self-host the web interface is usable on mobile through the browser




You could almost manufacture it based on this image, granted that’s a 1/4" impact bit. All it would take is one bolt being smuggled to their factory or one photograph of a spec sheet.
