thingiverse
This is a 1/2-inch spacer for punching six holes in the standard North American face shield visor design found at 3dprint.nih.gov/discover/3dpx-013306. It fits my Swingline puncher and may fit others if the part below the clip is shortened. Print this with the clip on the bottom, then flip it over as shown to install. To install, simply clip it onto the vertical sheet metal part located at the left edge of your punching setup, which you use to hold material in place for punching.
