3D PRINT/SURVIVAL PROJECTS FOR

'THE DAYS OF CORONAVIRUS'

= courtesy of JET Energy, Inc. and The Obtundia Company

Private 3D printers and Companies have vastly stepped up to create masks, respirators and changes. Now you can, too.

Many uses for your computers.

.... And 3D Printers. Grab your filaments. Attached are 3D printing hints, locations, STL loci. Anyone with a 3D printer nozzles open can help.

Want to ad a url, stl, contribution, suggestion or correction, email 3d4corona@nanortech.com

These are six (6) ideas/prototypes, not proven safe, but 'bread' for adult thinkers. There is no warranty or promise made.

Thank you. Stay safe.

Project 1: NIH Approved Face Shield

The NIH just accepted this design. <====

NIH Approved 3D-Printed Face Shield Design For Hospitals Running Out Of PPE
https://3dprint.nih.gov/discover/3dpx-013238

Most importantly, this one uses standard US report cover or transparency material
as a shield. can use: clear mylar, PETG, PMMA cut to 8.5 " x 11". DO NOT CUT PVC.
SPEC: 2 to 10 mils / .05 to .25mm

Then use a three hold binder punch for three 6-8 mm diameter
holes center spaced 108mm apart. some discussion here:

Project 2A: Structural Parts of ad hoc Face Masks

Medical suppliers were void of face masks, as is Home Depot - usually carrying dozens of lines of product.
So, this is a serious emergent issue to consider.

For those interested and with 3D printers, several types are here:

Printed prototypes from future possibly useful surgical masks
with perhaps activated charcoal and the like in series with the filter.

Project 2B: Filtration Parts of ad hoc Face Masks
Homemade N95 Masks In A Time Of Shortage

https://hackaday.com/2020/03/18/homemade-n95-masks-in-a-time-of-shortage/
"Due to the worldwide pandemic of COVID-19, there has been a huge shortage of N95 masks. [Paddy Robertson] from Smart Air has been working on designs for a DIY N95 mask that may be able to protect those who haven’t been able to secure their own masks. While there may be an abundance of memes around the various material people have been able to use to substitute for the filters, there is some very real science behind the sorts of materials that can effectively protect us from the virus.
According to a studied performed at Cambridge University during the 2009 H1N1 flu pandemic, while surgical masks perform the best at capturing Bacillus atrophaeus bacteria (0.93-1.25 microns) and Bacteriophage MS virus (0.023 microns), vacuum cleaner bags, tea towels, and cotton T-shirts were not too far behind. The coronavirus is 0.1-0.2 microns, well within the range for the results of the tests.As it turns out, cotton homemade masks may be quite effective as alternatives – not to mention reusable. They also found out that double layering the masks didn’t help with improving the protection against viruses. On the other hand, one significant design choice was the breathability of the material. While vacuum cleaner bags may be quite effective at keeping out small particles, they aren’t as comfortable or easy to breathe in as cotton masks. Have you tried making your own cotton masks? In a time when hospitals are running low on surgical masks, it’s possibly the best option for helping to keep much-needed medical supplies in the hands of those helping at the front line."

Project 3: Folding@Home Project for Unused Computer

The Folding@Home project started back in 2000 and has helped with, and identified, drug therapies for Alzheimer’s and Huntington’s disease, HIV and influenza.
IF you have computing power, consider adding on. This takes less than a quarter of a microcentury (~14 minutes) to read up, install, and log in.
