I remixed this model to fit bigger phones and i added a place for an elastic strap for added security. Please give all the original credit to HideaKi at Printables who is the original creator of this clever design.

The cup holder and clip is the original and fit my phone bigger holder remix. (Of course)

Hope you like this remix.
