Here is a model of adjustable protective visor that does not use a rubber band.

A knob at the back allows you to tighten the set with enough force to hold the visor, you can even run with it !

The assembly can be done entirely without screws, however I have provided a small screw to hold the wheel, but it holds well without.

Of course it's a model that requires a little more printing time but not much more, the strips are very thin, I use a hair dryer to bend them more easily, the same to crimp the A4 plastic sheet.

I remain at your disposal for any questions, modifications, improvements and so on....

Here is the video for the visor assembly:
