If you want to fit a wider elastic strap to a Prusa RC3 faceshield these will clip on each side and have a vertical slot for the strap that goes around the back of your head. The slot is 21mm long and so will take for example the elastic strap from a head torch, or just plain wide elastic from a roll. They secure by pressing them down from above and they are labelled (L)eft and (R)ight.
A very small amount of filing may be required.
