Universal Phone Shade for Sun, Glare Shield

I designed a universal phone shade, so you can enjoy your phone at the beach by actually seeing things on your screen. I tried to print some pins in PLA but it doesn't get enough friction to hold the cover in place. So just use a regular screw, bolt whatever that will work as a pin. 

Scale up the cover as you like so it fits your phone better, make sure to scale not uniform, so the height(z) remains same. 

If the clamps are too big, just briefly push the feet together with your fingers like shown in the picture, they will deform good enough to be tighter thanks to their shape/design. 

I didn't want to spend so much time on optimizing the design, so feel free to remix, update, improve the design as you like.
