Mask Bridge (Maintain breathing space under an Olsen mask.)
thingiverse
On 3D Printing Useful Things group on facy, somebody was asking for an STL for one of these, so here's a bit of Friday night designing from "downunder" to help the global community at large. The World Health Organisation now recommends widespread community use of face masks as one of many measures to reduce the spread of COVID-19. When it comes to homemade, sewn cloth Olsen pattern masks seem to have the best fit from my experience, but some people like a bit of support to maintain an airgap between mouth and mask. This bridge piece is a free, open source design, and is fully parametric with the openSCAD file included. Feel free to copy, resize, remix or improve it. You will need supports under the bridge sides, but probably only "Touching Buildplate." PETG recommended, as it is more resistant to more methods of sterilisation, but you might get mileage out of PLA if you'd prefer.
