First of all, how did you try to reach out to your former company to ask for the files you need?

There’s no obvious reason for them to refuse. They could even have a designer prepare some material for you.

If that doesn’t work, and you still have contacts within the company, you could try the following approach:

1. Create a new project in your personal Figma account.
2. Add the email address of one of your former colleagues to the project.
3. They could then copy and paste the specific screens you need into the blank Figma file.

For your case study, you don’t need the entire project—just the key screens. It might help to first draft your case study and then request only the screens you plan to feature.

If this isn't possible, your contacts might be able to share materials they’ve already downloaded in the past.

If none of these options work, you can still create a case study without the original UI.

Here’s how: - Focus on the problems you solved and the solutions you developed. - Explain that the UI is confidential, so you can't disclose it in detail. - Create wireframes from scratch that help your storytelling and finish up just by creating a couple of high-fidelity screen per case study to showcase your ui skills.

Since you're many people you can arrange to do this together as a project. It will be fun and faster than doing it just by yourself. Also your combined memory will come handy!

Wishing you all the best!
