Combination of a 3D printed frame based on the Prusa design with a laser cut shield.

The design of the shield enables stacking similar to the Prusa design, and features extended wings for more side coverage, and a fold over top with tabs to provide a top shield against aersol drop. The shield is also taller with an adjusted inner curvature for extra comfort and reducing dependency on foam. In a pinch, this design is fully compatible with Prusa pattern face shields and 3 hole punched transparencies, but works best with the provided cut file.

Pre- and Postprocessing Instructions

Printing is recommended for speed with a .3mm layer height and a .2mm seperation between frames when printing in stacks. Support does not appear to be needed for this design, even for stacks. Batches of 5 per stack seems to work well. Additionally, a 1.2mm wall width appears optimal.

For the shield, we used 5mil PET plastic on a FSL laser. It is possible to stack the material and cut more than one at a time.

For fastening, use either rubber bands or elastic wrapped around the anchors.
