Tinker Pi Factory is Now Making Covid-19 Masks

Sponsoring Bedford-Stuyvesant Volunteer Ambulance Corp in Brooklyn NY


We have converted the Tinker Pi Factory into a mask making machine! I am from the Great State of New York, so I'm pleased to be sponsoring a few of my fellow New Yorkers during this difficult time -- The Bedford-Stuyvesant Volunteer Ambulance Corp.

Help Us to Sponsor Bedford-Stuy!

alt textThe Bedford-Stuyvesant Volunteer Ambulance Corp (BSVAC) was founded in 1988 by James (Rocky) Robinson in response to a lack of first aid services in the area. BSVAC was the first minority-owned volunteer ambulance corp in the US, and has trained hundreds of young men and women who have graduated from their EMT program. I was approached by Deputy Chief Tyreem Smith, who was trying to find PPE wherever he could. "We're really struggling to get supplies from the city", he said. We had been printing the masks for a couple of weeks, and I wanted to find people who could really benefit from them. Since we are not charging for the masks, donations are greatly appreciated so that we can continue to pay for supplies!.

You can support us by donating, or by purchasing the products on this page. We recieve a small commission from Amazon when you do!

The Hepa Mask

The Hepa mask was designed by xxx posted on Thingaverse here. This is one is the more protective of the two. We found HEPA filters on Amazon here:
