I call it the 'Eye Cu Smile' face covering prototype.
Named because it was designed to bring smiles back into our daily lives. Especially for the vulnerable and disabled children confused and perturbed by this strange new world we find ourselves in.
It has self-disinfecting Copper3D PLACTIVE filter mesh cartridge, hence the Cu.
Simply print a one off of the face covering kit in your size in pet g. Doesn’t have to be transparent. Then get a big Zip lock bag to use as the material and follow the assembly instructions in the attached PDF. Then use 2x the filter in this remix listing.
See attached pdf for detailed printing instructions. Different settings are required for the Filter Mesh.
A simple concept. I saw screw in filters for paper masks such as the excellent mask filter v3 https://www.thingiverse.com/thing:4323661. I have friends and family with children with disabilities, that and I was starting to feel really anxious in public. I figured out its because I can't read peoples expression. I'm so used to smiling at strangers and getting a response back. But now we live in a world of confused and suspicious eyes. I stumbled upon the Hens nest V3 from the university of Delaware. Used a zip lock bag I used to pack PPE in, big n tough, the hens nest v2 and the mask filter v3 to make a successful prototype transparent face covering in PLA. It cracked and broke shortly afterwards but proved the concept.
Hence why I developed the flat pack face covering system. So I could make 50 face covering kits with hydroknit shop towels a week, but also make a couple of transparent variants a week for those most in need. Its why the ribs are shaped as a cross, to form a window to the face for this remix.
I've been testing it at work and in public for a few weeks now. The response I get when people see me smile is almost always overwhelmingly positive. Even if most people are baffled by the bag on my face. I still consider this a work in progress prototype but have run out of time to develop it further. Hence why I'm posting it as is for the community to improve upon.
This listing is just for the filter housing and assembly instructions.
If you wear this face covering it is compulsory to smile in public :) Let's bring small moments of personal connection and happiness back to people's lives.
-Zip lock bag size required-
For Regular frame size:
Minimum size zip lock bag: (11" x 16" - 279mm x 406mm)
Suggested size bag used in pictures: (15" x 20" - 381mm x 508mm)
Assembly is much easier if you have lots of excess material to work with as with the suggested size.
Other flexible plastics can be used but heavy duty zip lock bags tend to be tough and cheap with a double wall.
-Opportunities for improvement-
Several opportunities for design improvement have been identified after feedback and are at the end of the assembly instructions. I'm out of time and am asking the community to help with these if they can.
Due to the smaller filter area of this design it is advised that people with breathing difficulties do not attempt to use this face covering. I would also not advise giving them to children.
If at any time it feels like your breathing is being restricted and you cant get enough breath then take off the face covering immediately and check that there is nothing blocking the filters. If the problem persists select a face covering with a larger surface area such as hydroknit towel on the standard flat pack face covering kit.
It is not advisable to use n95 filters in this housing as they will be too restrictive, they are designed for use with surgical mask cut out discs, hydroknit shop towel cut out discs (4 ply) or cotton make up pads. For n95 or HEPA level filtration the filter will need to be redesigned for a larger surface area.
Humidity will build inside the sealed plastic air volume over time as it cannot escape through the filters. This would be solved by adding a vent but that defeats the point of wearing a face covering that protects others and doesn’t meet with UK advice for shops anymore.
Guidance on how to prevent the face covering misting up and to address the humidity are in the assembly instructions. After more than a couple of hours of use it is likely the face covering will need to be removed to let the humidity out or it could start to make breathing uncomfortable due to the high humidity within it. This is the case for all N95 masks without a vent. This could be particularly uncomfortable for people with lung conditions such as asthma.
-License and selling of face covering kits-
We share these files under non-commercial license. It would be great if you donated these face covering kits to those in need for free. If you need to cover your production costs, we are ok with you selling the face covering kits for production cost. However, we do not want to see these kits on eBay or amazon for extortionate costs. The design is open to the community for modification and improvement. You do not need to accredit me with the design. I just want to get it out there for others to use and improve upon.

Production & Certification
These flat pack face covering kits are made to a common design but are made from various brands of PET-G plastic and on multiple types of 3D printer. This type of frame based face covering kits are widely used in large numbers around the world to combat the coronavirus pandemic. However, the face covering design supplied in this pack does not have regulatory approval. Hence these flat pack face covering kits are considered for temporary emergency use only when no other PPE is available. Potential users should consult their guidelines and procedures regarding the use of non-standardized PPE before using these flat pack face covering kits. The plastic of the frames has a limited lifespan and will degrade with successive use, hence they should be viewed as temporary and disposable.
