Adjustable headband
thingiverse
Since I couldn't find a rubber band to hold the Prusa face shield in place, I created an adjustable headband instead. The middle section needs to be secured to the bottom part by inserting a soldering iron or similar heat tool through the three holes of the middle part and into the bottom part. Then, apply pressure along the circular edges of both parts to "weld" them together. Additionally, you'll need to poke a hole in the wheel and clean out any debris that may be stuck inside. The "strap_for_face_shield" file is designed to fit on my customized Prusa face shield, which can be found here: https://www.thingiverse.com/thing:4301727
