Figured out how to make a pull request

Hi! I've recently made a Ukrainian translation for the DE and it would be cool if you could add the translation to the official version.
uk_ua.json

Also, of-topic question (if needed, I'll create a separate issue thread): Is there a possibility that you will bring back the old 3D tools models, as an optional feature? I just personally like them more than new models.
