Current findings indicate that face masks provide more protection in the Corona crisis, and above all prevent the risk of infecting others. The supply situation for these masks is, however, currently difficult. In addition, professional protective masks need to be reserved first and foremost for people working in hospitals, medical practices and the emergency services.
Motivated by these considerations, the EDAG Group have developed "mask4all" for everyday use.
Combined with standard household fabrics or the kind of medical non-woven materials that are available over the counter, the kit can be used to assemble face masks to help to contain COVID-19. The self-assembly masks are intended for commercial customers, municipal facilities and private individuals, to relieve the critical supply situation.
The "mask4all" has been specifically designed by the EDAG developers to be practical, functional and sustainable. It consists of holder elements, and between these just about any type of woven or non-woven fabric can be held in place. This saves the time-consuming job of sewing masks. The fabric can also be changed or washed regularly and quickly. We have compiled the list of standard, suitable fabrics that most households will have on this page.
The fact that it is reusable makes the "mask4all" a sustainable solution.
In order to enable not only the 8,500 employees working for the EDAG Group, but also other customers to have access to large quantities of "mask4all", corresponding agreements have been concluded with two companies, Möller Medical GmbH (Fulda) and Göttlicher GmbH & Co. KG (Schlitz). Since mid-April, the project partners have been producing large quantities of the "mask4all" in an injection moulding process, and are marketing them in sets via their sales channels and partner companies. You will find the contact details at the bottom of this page.
For private customers, we have also made the 3D print data for the mask holders available for free download on our website. Alternatively, anyone who doesn't have a 3D printer, can order the parts from our 3D printing partners.
With this initiative, we want to make a pragmatic contribution to overcoming the Corona crisis.
Keep cool and optimistic, and above all stay healthy!

The effectiveness of the mask depends more than anything else on the fabric used and how it is fitted in the clamps. It is therefore not possible to rule out the risk that you might still be infected or infect others even though you are wearing this mask. It is also necessary to practise putting it on and taking it off, so as to avoid transferring the virus by touch. How well the clamps work also depends on the material used for the clamp. When downloading the 3D print data, therefore, you declare that you will be using the mask at your own risk.

Downloading the 3D print data means that you declare that you will be using the mask at your own risk. It also means you obtain the rights to use the files only for your own use and non-commercial purposes and in particular not for the purpose of production for sale.
Download the 3D print data and use it for your own 3D print.
If you do not have a 3D printer available, let a manufacturer of 3D printed parts have the 3D printing data.
Select a fabric type. The standard recommendation here is to use a T-shirt or pillowcase.

Template for mask fabric
Lay the fabric on the table with the outside facing downwards, and lay the catches on it with the latches facing downwards. If necessary, the upper end of the textile can be folded over.
Align the adapters on the table with the lettering facing downwards and the eyelets facing outwards.
Slide the adapters under the fabric and clip the catches into the adapter opening. In this way, the fabric is caught between the adapter and the catch. Apply gentle pressure until the catch is pressed right into the adapter. Repeat this process for the other side.
If you now turn the DIY mask over, you can see the clamping point where the fabric is firmly clamped between the catch and the adapter.
The last step is to attach household rubber bands or strong threads to the eyelets, enabling the DIY mask to be secured behind the ears or around the head.
