This is a re-mix of the Chicago Shield Frame for 3D Printers with beds bigger than 181 x 147mm. This version is a 15 stack to match the 15 stack of Chicago Shield Frames. It uses the same zip apart serration geometry. In addition to the STL file, pre-sliced g-code for Prusa-MK3 and Flashforge Guider II 3D Printers running PLA Filament are posted here.
If you slice this stack it must be sliced at 0.3mm layer thickness for the serrations to work and be printed properly. Many slicers will slice the first layer slightly thinner or thicker. Check the first layer height to make sure it is indeed 0.3mm.
This design has the same dimensions as the 3D Printed Face Shield by Limitless Studio in Chicago. This Face Shield design is widely accepted by Chicago area institutions as stop gap PPE.
