Stencil for a reviewed PRUSA Face shield

thingiverse

This project aims to review the PRUSA Face Shield model (https://www.prusaprinters.org/prints/25857-prusa-face-shield), making prime materials easier to find and speeding up production and assembly processes. In this version, the shield is a common 0.15-0.30 mm PVC sheet, widely used for books, easily accessible online or in any stationery store. This range of thickness, unlike the original one (0.5 mm), does not require holes on the bottom part of the shield because the right interference with the lower plastic part is already enough to keep it in place. Inserting the original A4 format PVC sheet into the Stencil allows drawing the external contours of the shield, cutting them easily with scissors. Using the upper holes makes it possible to draw their positions and cut them with a belt punching machine (https://www.amazon.it/fustellatrice-Professionale-Fustella-perforazione-intercambiabili/dp/B015J1FJCS/ref=sr_1_6?dchild=1&keywords=punzonatrice+per+cinture&qid=1587249564&sr=8-6). Alternatively, using a common 8 cm paper punch (http://www.ellepioffice.com/perforatore1.html) allows drawing the shape of small triangles in the upper part of the Stencil and aligning them with the central reference found on every paper punch. This solution is faster.
