Mask extender

thingiverse

I tried to print various mask extenders, but this one is simply elegant. Print with clear material, 0.2 -0.3mm. To improve against breaking, try printing with 1 wall and 100% infill rather than only (3) walls. To further improve stability, melt object(s) (if on glass printplate) directly after print finishes with a torch to re-flow slightly. Then let cool down. Then give to people :-)
