“Rowan University engineering and medical students have developed a prototype for a durable, lightweight, reusable face mask to augment the supply of face masks during the current shortage…”
“The prototype provides two components: a contoured mask and filter housing. No special tools are needed for assembly. The replaceable nonwoven filter materials recommended for the filter housing are widely available. Users will supply and install the elastic or cord.
The mask can be printed in three sizes, all with the same size filter housing. The contoured mask may be more closely molded to the user’s face by submerging the edges in hot water and pressing it to reform the shape against the face.”
A link to the Rowan website.
The website has detailed instructions for printing and using the masks.
I have printed several of the masks in both polylactic acid (PLA) and acrylonitriel/butadiene/styrene (ABS) plastic. Dolly and I have each tried the masks. Of the three sizes, we prefer the small . When printed in PLA the mask can be softened in hot 140 deg. F water and then molded to the face for a perfect fit.
Last Monday (03/30/2020) I relocated the Dream Weaver from Florida to Bishop Airport in Flint, Michigan. Then, I took our mini motorhome out of the hangar and drove back to Florida. Eight hours including two fuel stops going up; three days sanitizing gas pump handles driving South.
Michigan and northern Indiana were totally socked in. The photo is from 9,500 ft. Ceilings were 4000; scattered 1300 ft. Outside air temp flitted between 27 and 32F. When ATC cleared me lower for the approach I dove at 2,000+ fpm to pass through the layer as quickly as reasonable. Even so the plane picked up some light rime ice on the leading edges and windscreen. Fortunately it quickly melted below the deck. The approach and landing were uneventful.
The relocation was done because the plane is ten months into its last twelve month condition inspection; all of my tools and hangar are in Michigan, while Dolly and I expect we will be stuck in Florida till late July.
It was forecast to rain today. So, I harvested these from our hydroponic garden. I should have placed a ruler in the photograph. The central tomato is about 3-1/2 inches in diameter. Add lettuce, raisins, craisins, dried cherries, shredded cheese and salad dressing. Yum…. Eat Healthy. Next week I’ll put on a mask and gloves to go grocery shopping for several head of lettuce.
