Case encoder reusable mask

The aim of this project is to solve a problem thank to 3D printing. I regularly use a reusable mask but do I really count the number of uses ? Absolutely not ... and this is not good at all because every time you forget it’s an extra use. So I propose you a mask protection with encoder to not forget anything. I made as ergonomic as possible and pratical. You can let the rubber bands out from above. I hope you find it as useful as I do.
