Chest mount phone holder

My phone is 156 x 75.8 x 9.6 mm (6.14 x 2.98 x 0.38 in), this model was made to fit that.

I used the straps from my old backpack. Just a few minutes to sew by hand.

Also needs this rubber band to hold the phone in place.

I added supports manualy to the front and the back.
