Missing License
The project is called OpenSourceMask, but there is no Open Source Compatible license located in the root of the project. Technically, none of this is Open Source yet, just Source Available, and legally no one can do anything with the files, even produce, without consent.
Attaching a OSI compatible license will resolve this issue. The current trend with Covid-19 related projects is to use some form of a non-commercial license to prevent companies taking advantage, but that is technically incompatible with OSI standards. In the end its to the project to figure out what license you want to use.
Given the circumstances, I think a CC-NC license will be sufficient.
