Prusa Face Shield Lower piece multiple on a sheet

thingiverse

This is just a fast duplicate file STL. It lets you print up to 40 chin pieces at once with Prusa MK2, or mk3/s printers, all fitting perfectly on the bed. I highly recommend creating multiple G-codes with different placements and orientations to extend the life of your print surface. My own setup includes side-by-side prints, plus a 180-degree rotation, as well as smaller groups that allow me to adjust the number printed at any one time or prevent running out of filament mid-print. This design may work on other printers, but it's optimized for beds measuring 200x210 in x-y dimensions.
