The “dirt-bike” or sports dust masks are really popular. A lot of folks know them from using them at events like Burning Man and Coachella. The issue with a lot of “dirt bike” style masks is the exhalation valves which are totally unfiltered. This makes these masks pretty useless for COVID-19 safety. You can read more about what the CDC says about masks with valves.
Everything I used for this 2-min hack:
CLUX Mesh Black Face Mask with Black Carbon Filter by Continental Luxury (amazon)
small (not tiny) rubber bands – one for each valve
I assembled the mask according to manufacturers’ directions. I cut the filter fabric to go over the valve with a very generous overlap – you can always cut off the excess. Then I slipped the rubber band over 2 layers of filter fabric to secure it to the Valve. This covers the valve and any leaky spots around the opening.
So the issue with a lot of respirators and dust masks is the exhalation valve which is totally unfiltered. This makes them pretty useless for COVID-19 safety. You can read more about what the CDC says about masks with valves.
Check out the gallery below to see how I added a filter to my valve. I specifically added it to the outside so it would last longer before getting moist and so others could see it. I used two layers of material for the filter.
The new reality around COVID-19 safety has us all scrambling to create new habits while we go about the business of making things. We are currently trying and experiment with tool caddy’s. The idea is:
Come into the shop, and pick up a caddy
As you use hand tools put them in the bucket
Once you are done sanitize them and but them back
This way you don’t have to stop and sanitize with every tool and we avoid cross-contamination. Each bucket also has a small spray bottle of surface sanitizer and a personal pump bottle of hand sanitizer.
We are not sure if it will take all the sting out of the needed cleaning. We will see where the experiment leads!

Thank you to everyone who’s supported our efforts! As of today, we’ve collected over $21,000 and we’ve already distributed more than 80% of those donations to makers hacking solutions to the COVID-19 crisis.
This first update on our progress will explain how to read our dashboard and review public information that we’re sharing on our work. Future updates will be focused on stories from makers and those impacted by the generosity of our donors.
Our dashboard is hosted on Google Data Studio, which allows us to share key data while linking to optional data that some stakeholders might find interesting. In the image below, the fields circled in purple convey the most important information and the areas highlighted in pink help direct the reader to more information.
Additional data like money pending with GoFundMe or how projects have split out their support between materials, travel costs, etc. are available within Google Data Studio. The link in the lower-left side of the dashboard connects to a sheet with really detailed reports about where this money has been paid out. We love transparency!
We are slowly learning in a community that this thing will be a marathon not a sprint. So we are setting ourselves up with safer workspace practices to continuously offer the best most immediate help we can. We are also learning to celebrate everyone’s efforts even when is just nibbling at the problems.
Without further ado here are just a few snapshots of AMT members in action while we work to help people directly and in partnership with our fellow makerspace and non-profits.
While we have done our best to collect information from reputable sources, we are not industrial hygienists or medical professionals. We are doing our best to be helpful in a crisis situation. These guidelines are provided “as-is” and come with no guarantee that following these guidelines will keep you 100% safe. Use at your own risk, use combined with your own judgment, and refer to the latest scientific information available.
In the past few weeks, Makers everywhere have stepped up to help deal with the COVID-19 pandemic by making Personal Protective Equipment (PPE) to help keep healthcare professionals and other vulnerable people safe. However, makers becoming sick themselves, spreading the disease, and contaminating their workspaces adds to the problem and not the solution. We are providing these best practices, gathered from medically reputable sources (such as the CDC) in an intent to provide a means of decreasing the risk of makers spreading and contracting COVID-19 while in the process of making DIY PPE.
It is very important that you control and track who is in the makerspace and when. The following is practical advice.
Keep isolation protocols. If people are not already living together they should not be working in the same room without masks being worn at all times.
Keep 6 feet away from each other in hallways and common spaces.
Sanitize items handed off between individuals as much as possible
Make sure all people in the space making PPE are trained in the protocols for your space before allowing access (example: AMT COVID-19 Access Protocols – will link)
First and foremost, please do not attempt to make any PPE if you or someone in your household is sick. Even if you have a small tickle in your throat, please do not make any PPE if you think you, or someone that you are exposed to may be sick.
Act as if you were infected by the COVID-19 virus. Wear a face mask and a fresh pair of gloves when collecting each piece of ready-to go PPE. Store the PPE immediately in a sealable bag.
Keep your distance: Remain no closer than ~6ft (2m) from another human
Wash hands for at least 20seconds with soap and water before beginning work or handling materials.
Don’t touch your face
Cough or sneeze into the crook of your elbow
Sanitize your work surfaces and tools before and during PPE creation
Sanitize your cleaning equipment when washing fabric PPE and PPE materials
If you can, please segregate the tools and equipment that you will be using to make the PPE in your space away from people, pets, bathrooms, or food preparation surfaces.
Always disinfect between users.
There is still debate about how long the virus survives on hard industrial surfaces, but it is currently estimated that COVID-19 can live on hard industrial surfaces (metal, plastic, and glass) for up to 3 days. If you have access to sanitizing solutions, including diluted bleach, 70% alcohol solution, or products like Star-San or Odo-Ban, please disinfect your tools and equipment before and after each item is made. You can also let packed items sit for 3 days before distributing, as another mechanism to reduce the risk of transmission.
For 3D printing:
If the machine is clean, the plastic is heated up enough to be considered clean once the print is finished.
Do not attempt to sterilize the finished part; just drop in a clear bag with gloves or tongs and set aside.
Many sterilization solutions will damage PLA, and off-the-shelf isopropyl alcohol is not concentrated enough to clean the parts
Store similar to N95s (allowing the mask to hang in a designated area or placed in a paper bag and labeled – with one mask per paper bag).
Launder after each use.
Do not use bleach to sanitize metal equipment or tools as it will corrode most metals.
If someone working in the space displays symptoms or is tested positive for COVID-19, the workspace must be thoroughly cleaned and disinfected to avoid further spreading the virus to others.
Cleaning and Disinfection After Persons Suspected/Confirmed to Have COVID-19 Have Been in the Facility
Cleaningrefers to the removal of dirt and impurities, including germs, from surfaces. Cleaning alone does not kill germs. But by removing the germs, it decreases their number and therefore any risk of spreading infection.
Disinfecting works by using chemicals to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs. But killing germs remaining on a surface after cleaning further reduces any risk of spreading infection.
It is recommended to close off areas used by the ill persons and wait as long as practical before beginning cleaning and disinfection to minimize potential for exposure to respiratory droplets. Open outside doors and windows to increase air circulation in the area. If possible, wait up to 24 hours before beginning cleaning and disinfection.
Cleaning staff should clean and disinfect all areas (e.g., offices, bathrooms, and common areas) used by the ill persons, focusing especially on frequently touched surfaces.
If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to disinfection.
For disinfection, diluted household bleach solutions, alcohol solutions with at least 70% alcohol, and most common EPA-registered household disinfectants should be effective.
Diluted household bleach solutions can be used if appropriate for the surface. Follow manufacturer’s instructions for application and proper ventilation. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. Unexpired household bleach will be effective against coronaviruses when properly diluted.
Prepare a bleach solution by mixing:
5 tablespoons (1/3rd cup) bleach per gallon of water or
4 teaspoons bleach per quart of water
Products with EPA-approved emerging viral pathogens claims are expected to be effective against COVID-19 based on data for harder to kill viruses. Follow the manufacturer’s instructions for all cleaning and disinfection products (e.g., concentration, application method and contact time, etc.).
For soft (porous) surfaces such as carpeted floor, rugs, and drapes, remove visible contamination if present and clean with appropriate cleaners indicated for use on these surfaces. After cleaning:
If the items can be laundered, launder items in accordance with the manufacturer’s instructions using the warmest appropriate water setting for the items and then dry items completely.
Otherwise, use products with the EPA-approved emerging viral pathogens claims (examples at this link) that are suitable for porous surfaces
Linens, Clothing, and Other Items That Go in the Laundry
Do not shake dirty laundry; this minimizes the possibility of dispersing virus through the air.
Wash items as appropriate in accordance with the manufacturer’s instructions. If possible, launder items using the warmest appropriate water setting for the items and dry items completely. Dirty laundry that has been in contact with an ill person can be washed with other people’s items.
Clean and disinfect hampers or other carts for transporting laundry according to guidance above for hard or soft surfaces.
We have been cutting parts for the last couple of days for local health care folks for the Bay Area Medical Faceshield Emergency Production. Currently, they have a private Facebook group for contributors and a public facing GoFundMe campaign.
This amazing group will have a website soon but currently are focused on meeting the need and getting design verified by healthcare folks. Stay tuned for more news about this project.
