This is a hack, a flat version of the face shield protection designed by the portuguese group of volunteers https://3dmask-portugal.eu/
To be printed in PTEG with 50% infill and 3 walls (for a 0.5 mm nozzle printer).
The idea is to print a stack! Height is 0.5mm.
OpenSCAD file available!
For layer height of 0.2mm use the models Nxfshield-layer0.2mmm.scad.stl, for n=5, 10, 15
