Personal protective equipment (PPE) is in short supply due to the COVID-19 pandemic.
There are tons and tons of awesome PPE designs on Thingiverse, YouMagine, Instructables, and other popular hangouts for makers. One that I really like is this facemask that uses a plastic report cover or overhead transparency made by Erik Cederberg / 3DVerkstan from Faceshield.nu. Unfortunately, it was physically too large to print using my 3D printer, so I made a version of his design that can be cut using home CNC mills, like my Carvey. It can be cut in just 11 minutes! I used a 1/4″ thick MDF sheet, but any flexible but strong material should do the job.
SHARING THE SOLUTION
Head on over to Inventables right now to grab the Easel project/G-code! My employer is also printing these same masks in our company hackerspace, so I intend to bring them in as part of their drive to produce PPE and donate them to those who need them.
