Universal Phone Mount V2: Bike, Car, Tripod

This is one of the most useful things I've ever printed. This dock firmly holds any normal sized smart phone and can mount to your bike, hang from your car rearview mirror, or mount to a standard tripod.

I used it to hold my phone to my bike for doing speed tests on my latest project, the Bicycle BoosterPack. (A near-universal clamp on friction drive E-bike kit) Check out the instructables here: http://www.instructables.com/id/Bicycle-BoosterPack-a-3D-Printed-Portable-Electric/

Non-printed hardware required:
(1) hose clamp,
(1) hex bolt 4" long
(2) 1/4" hex nuts
(1) spring
(1) nylock 1/4" hex nut.
