Two photos: One is a set of breaking fixtures, as I like to call them. I created them for the purpose of strength testing my new glass-based material. The older, smaller breaking fixture is at top, followed by the larger, later fixture. Below that is a bar of my new material. Below that is a mold for casting such bars. I cover the mold with aluminum tape to increase moisture retention. The second photo is the breaking fixture in action. The force sensor is FC2211-0000-0025-L from Mouser.

Face shield 3D prints. The orange one (top) was printed with PETG at 0.35 mm layer height. The grey one is PLA printed at 0.2 mm layer height. The PETG print has some imperfections in it, but using the larger layer height cuts an hour off the print time. These are both the NIH version for the US, which is a remix of the one designed by Prusa Research, who made my Prusa i3 Mk2 printer.

First ever print with PETG filament. I'm pretty happy with how this material printed. The resulting parts are supposed to be more durable than PLA, and be able to survive higher temperatures.

Josef Prusa is not a big fan of printing N95 masks either. His company has been focused on making face shields and hand sanitizer.
