An elementary class asked me to make these to replace the clips they were losing during the pandemic. These clips attach to a ball cap. The centre clip of course goes in the centre while 2 side clips go on either side of the brim of a ball cap. Attach a transparent shield of some sort (any clear plastic will work) to the bottom of the 3 clips and this will somewhat protect others from your coughing. This is not approved my medical professionals and was only used temporarily in an outdoor setting where students were social distancing.
The author marked this model as their own original creation.
