This model is based on the [Verkstan 3D-printed protective visor](http://3dverkstan.se/protective-visor/) ([CC BY-SA](https://www.youmagine.com/designs/protective-visor-by-3dverkstan)). The model has been refined by the University of Edinburgh's [uCreateStudio](https://www.ucreatestudio.is.ed.ac.uk/) for single filament stacked printing. These stacks separate easily with a scraper/spatula. A small amount of postprocessing is advised, spending about 10 seconds per mask filing the under surface. gcode files for use with Ultimaker 3 3D printers, with a single 0.8AA nozzle and PLA filament, can be downloaded directly from [uCreateStudio](https://www.ucreatestudio.is.ed.ac.uk/3d-printing-ppe-stacked-3dverkstan-visors/).
