That's definitely a challenge... I lucked into hearing about the group I got hooked up with here in BC, Canada. We're organizing using Slack, and have a central couple of people who are managing the supply chain and tracking who has what inventory. When inventory gets to a high enough level, we arrange for someone to do a drive by and pick up all the inventory in an area.

Someone else is managing requests for product, and tells the delivery drivers where to go once they have them.

You might want to get in touch with a local makerspace, or maybe a community college that has 3D printers? I see many of those are involved in these initiatives around the world.

The ones I am making are free to those using it, not to me (the one making them).

I am trying to help a little, and have some fun while I am at it. At the end of the day we are both helping and should do so however we feel is right. Just like the young man that got this particular project going.

My local hospital is taking all that I can print, done over 100 so far and got more on the printer now. I can print 14 at a time and it takes about an hour.
I am using ABS , 100% fill, .1mm resolution.

my printer will be here tomorrow, I've wanted one awhile anyway. I've got a spool of PTFE coming, trying to keep the smell down. We'll see if I can make it print OK and then I'll make some calls. I'm working 5 on, 10 off and have been looking for things to do anyway

Default Update on Hudson's production line

Hudson has been busy keeping his printer running. Kristy (mom) got to work yesterday and some other groups had dropped lot of headbands at the hospital. The immediate demand there has been met.

I had been contacted by a doctor's office to get some of the bands so we will be dropping some by on Monday. Several of the primary care offices are still working seeing patients. A friend who owns a pharmacy requested another printed mask frame for his staff. Hudson will be cranking those out later today. I will see what else they need and Hudson can focus his production on the smaller medical facilities.

Our cousin works in a nursing home in Mobile and has requested some also. We sent a dozen out to her last week. We will get another fifty or so in the mail Monday to them.

Its great to see how quickly people come together to meet needs and solve problems!
I will be sporting my Vans logo mask strap tomorrow when I go back into the hospital for my shift. Proud of my kid and what he has done just because he wanted to do something to help.
Thanks to everyone. Stay safe and isolate!

Default Dentists can use these too.

Once we get past the medical crisis, keep in mind we will need to get the dentists back to work. We are shut down except for emergencies and due to the shortage of PPE, it will be risky getting even the emergencies taken care of. These can be used along with rubber bands to jerry rig some better masks and maybe get back to work sooner. Check with your dentist once the real docs are taken care of.

I've only got a little makerbot knockoff that only has room for 6 at a time but I've made about 150 over the last few days. I've got several doc friends here in Portland and these are a hit so far.
