it's well known that we carry our smartphones everywhere and all the time...when running, travelling, goin out, etc.. this holder lets you go light... while still carrying everything you need..perfect fit on oneplus one... hope you like it.. hey people.! i just uploaded new documents all of them have reconstructed geometry in their meshes..plus a new version that has a 1.2 mm uniform thickness for better pintability.i also uploaded a separated case from the clip... wich enables you to design your own clip and/or design and attach to the holes in the case any other accesorie that you might print..enjoy...
