This is an adjustable sun visor extender that I made for my short wife when the sun is low in the sky.

It has clips which slide onto a frame and the visor is adjustable in steps. It is 10" long and 5" high. The clips are rather large, but they are pretty strong and won't slip (from my intial testing).

There are two small holes in the adjustor arm for a loop of string, or a piece of filament so you can easily pull the adjusting arm out of the hole it is seated in (a piece of filament can be riveted in by melting the back side).

The holes in the visor are just to keep the piece from sticking too aggressively to the printer bed.

This thing will probably warp in the summer, but I guess I'll find out then.

Print it. I used 20% infill.

Scale it down if it is too big.
