This is a remix of, "DtM-v3.1 Face Shield PPE, NO LOGO, Fixed Width, 3 Peg Version" (Model ID 3DPX-013597). Our group #3DPPGH is always looking for an optimized model so that's what I created. I added a chamfer along the bottom edges of the print so if the first layer overextrudes, it will not create a sharp layer that might dig into the wearer's head. I also created fillets at various points in the model that were prone to crack propogation. I added fillets to the corners of the splatter gaurd, because FDM 3D printers don't like sharp corners in general. 

Overall, this model brings all of the attributes from the parent model, but the design is less prone to cracking in certain areas and is more easliy printed.
