Good tip…do you know how long under the UV it takes to sterilize something?
You can buy the wands and they generally come with instructions, depending on how strong they are. Usually it’s under a minute for non-porous surfaces like the mylar, but you’d need to read the instructions when you get the wand.
I’d feel perfectly comfortable just rinsing the mylar off, then washing my hands. (I might not even bother to sterilize it, rinsing it is going to knock the virus off of the mylar. But then I’d wash my hands after handling it. The problem is usually handling something that might have the virus on it and then not cleaning it off your hands before you rub your eyes or nose. I’m guilty of rubbing my eyes a lot during allergy season.)
Or you can rinse it and stick it outside in the sun. That might take longer to kill the virus, but sunlight is a great disinfectant.
Can also rinse the mylar then hit it with a spritz of alcohol and water, or vinegar and water, or thieves oil diluted, or ionic silver, or any one of a dozen washing methods. Even soap will wash the virus out of harms way. (As long as you remember to wash your hands.) 
Got another suggestion for everyone…my husband came up with this, and he uses it everywhere.
Keep a thin plastic bag in your pocket. (Produce bags are great for that, or sandwich bags. You could even use a large square of plastic wrap.)
If you have to go out into public to open doors or pump gas or press elevator buttons, slip the bag over your hand before you grab the gas nozzle or the store handle. Pump the gas, then toss the bag. It protects you from picking up whatever the last 50 people deposited on the nozzle or door handle, and it’s easier to get on your hand than a glove. It’s a great way to recycle your produce bags too.

Thanks. Last night I just filled two small spray bottles with bleach water to use when I bring new groceries inside. Do you think that would sterilize / disinfect the sheilds sufficiently or would the bleach do something weird to the mylar?
Haven’t watched this yet, but it looks like a good primer.

Yeah diluted bleach works as a great disinfectant too. (Don’t think it will damage mylar…I could check it but hubs ran off with the prototype.) 
Kottke covered some follow-up on that video:
Yeah same link, looks like.

Interesting video, and you can tell the guy is definitely a doctor. (I’m not sure how practical that much sterilization is for long term.)
I’ve added washing hands after opening mail and packages to the routine though, and tried to get mom to do the same. Already well versed in the “make sure the produce is washed before consuming” rule.

I have decided that the Foodi Machine is way too big for a two person household but wondering if those who have one unexpedly have an autoclave?

Which begs the question of having to reuse things normally tossed away. Before, the autoclave was the solution, then single use was a better solution. Now single use is not an option so why not go back to Autoclave.

if you are going to attach the mask to a cap the cap must be red with “MAGA” on it or it wont work.

That has to do with the ridiculous cost of the label “medical grade” tax on reusable stuff. It’s all fairly ridiculous to be honest. Qualifier, 4years as a central services technician.
Long term costs should be way down with reprocessing, but as with most things that means initial costs are higher and most people can’t rationalize or afford it. It’s also way easier to just buy single use(and it is handy inside kits).
The number of out patient practices that give me the willies just thinking about their sterilization conditions and techniques…please just buy single use…(source: people who left my hospital to work in those conditions-sometimes they can get them changed to…better at least, others…:shudder:

Didn’t have one of those handy, but I liked the airy mesh on the one that I used. Keeps it from getting too hot down here in the summer. 
DH has got boxes and boxes of fishing tournament related baseball caps. Most folks down here do have a few hundred on hand for hunting and fishing. Apparently you can never have too many baseball caps.
Thank you!
What are the power/speed setting you lot are using to cut the transparency films?
Now just make an N95 mask that looks like a bridal veil and, it will cost 100x!

Quick question- had purchased 0.30" PETG from US Plastics in hopes of making face shields for work at the hospital. I was able to download the laser cut only face shield plan, but have no idea how to use my Glowforge for anything but proof-grade. Do I take the tray out? What settings do I use? Any help appreciated as we’re running low on time!
I am collaborating with my local hackerspace and laser cutting PETG face shields to attach to face shield frames that are being 3D printed by other makers. Here’s what my process looked like and what I found worked for me.
- I set a piece of proofgrade draftboard down on the crumb tray to act as my base, and also the image of the shield template that gets burned into it acts as a nice placement guide for the PETG. Material settings were set to Medium Draftboard.
- I edited the face shield file so that any hole cutouts were a different color and would appear as a seperate layer in the Glowforge software so I could make sure those were cut first.
- The settings that worked best for the PETG I was using (.007") was 500 speed, 75/80 for power.
- I used spare pieces I had lying around to act as weights for the PETG and hold it flat.
- I cut one at a time.
Hope these notes help some other folks out there! Open to hearing suggestions/modifications to these settings/process. I’m not an expert by any means.
