Description

**V2.1 UPDATE can be found here: https://www.thingiverse.com/thing:4569285.** **V1.1 UPDATE** Changed to external lettering and thickened peg supports for easier printing. Stackable version without lettering can be found here: https://www.thingiverse.com/thing:4394121 Split design for smaller printers can be found here: https://www.thingiverse.com/thing:4400343. This was a redesign of "MNA Big Face Shield and Stacks--Chamfer Style" https://www.thingiverse.com/thing:4388797, which was a originally a redesign request of the "Face Shield Big Remix by ICU nurse" https://www.thingiverse.com/thing:4312120 by BlackDogCarbonFiber, which was based on the Prusa face shield. Huge thanks to ICU nurse Matt Behning, the original designer, for testing and approving modifications (and for many of the photos). Thanks also to Chad Schwartz for suggesting the tab concept and for providing consultation and encouragement in the redesign process. In order for these support tabs to work, be sure to select "print thin walls." Two 1-inch wide rubber tourniquets are used to hold the shield onto the wearer's head. A plastic sheet 12 inches wide and at least 9.5 inches tall is used for the face shield. Photos show a 12x12in plastic sheet. Files currently uploaded include stacks up to 10. Also included are single layers with and without tabs if you want to stack them yourself. Cura profiles for a 0.4 and 0.8mm nozzles are included. Still are works in progress but have worked on Creality printers. You might want to add acceleration control of 500mm/s; this will be added in the next profile update. Thanks to Alex Scheuerlein and Chad Schwartz for helping with this. When printing shorter stacks, the brim may not be necessary. This was designed to print with a 0.4mm or 0.8mm nozzle at layer heights in increments of 0.04mm (0.2mm, 0.32mm). Peg supports and tabs must be clipped and removed before use.
