Face shield cap clips

thingiverse

To produce crisp images for the summit of a lid, print 3 or 4 copies on an A4 transparent plastic sheet, such as acetate. Using a standard paper punch, create holes along the edge of the sheet. The primary advantage is that the sheet lies close to the rim of the cap, thus encircling the face more efficiently. Additionally, rounded edges have been incorporated, and both material usage and print time have been minimized.
