Summary

Be aware! Do not chage your phone while you use it in the bathroom or other places where water is present.

I have designed this, to mount my Doogee S60 in my car for navigation (it's a heavy weight phone and a normal holder didn't work), but then my girlfriend used it, to watch series when she's taking a bath. But you have to be carefull with this if your smartphone is not waterresistant you should not use this in the bathroom ... .
You can also use the clamp, to fix your smartphone on a tripod or something.

You will also need:

• 2 * 1/4" nut
• M4 nut
• hexagonal screw M4 x 60 mm
• spring that fits over the screw M4
• lighter (maybe you have to heat the nuts and M4 screw so they fit in the printed parts)
• tripod or

Hope you'll like it :)
