And you can, too My 3D-printed custom nose bridge. Images courtesy of the author I wear glasses (not pictured above for photo reasons), and for the last nine months they’ve fogged up every time I’ve gone outside.

For some reason, I haven’t been able to find a mask that’s comfortable and keeps my breath from blowing up into my glasses. Thanks to the magic of 3D printing, I’ve come up with a solution, and it works surprisingly well. And you can do it, too, if you have access to a 3D printer, some free software, and someone to help measure your face. (You can measure your face yourself, but that’s a little harder.) Here’s the plan: We’re going to make a tool to measure the curvature of your nose, and then use that measurement to design a custom clip to keep fog off your glasses. You clip the bridge over a mask, and since it contours exactly to your face, it gives the custom snug fit of a mask with metal wire, but in a more rigid material that won’t deform or unbend. This entire project is 3D printable, and should only take a few hours. The print time […]
