Sextant Tilt/Roll Phone Cradle

This phone stand with a nautical flair lets you both adjust the tilt angle and roll your phone left or right to landscape mode.  The spring-loaded clamp securely grasps your phone so you can poke at it without it rattling around in the stand. On most phones, the speakers, cameras, buttons and jacks are all unobstructed.

Requires 2 small rubber bands: one for tensioning the roll-joint to give you a smooth, uniform amount of friction, and a second for pulling the arms tight against your phone. Just pinch the ends of the two arms together to insert/release your phone. To tilt the phone, just lift the wedge out of the base and re-seat it at the desired angle. Because of the shallow wedge angle, friction holds the wedge securely in the base.

This is sized for a fairly large (75 - 82mm wide) phone. You can scale everything down for smaller phones.

Printed in PLA. The two arm parts need supports turned on, but the everything else prints without supports in the orientations shown.

Assembly Instructions

1. Slide the wedge into the base so that the circular knob is facing upward and is more or less horizontal. 
2. Gently flex the arms of the Clamp Center apart and slip it over the knob. The little notches in the ends of the arms should be facing upward. 
3. Double over a small rubber band and loop it over the ends of the arms of the Clamp Center. It should fit in the slots at the end. The Clamp Center should rotate smoothly on the knob. Adjust the rubber band tension (more or fewer loops) to get the level of friction you like. (See photo 6)
4. Each Clamp Arm (R & L) has a circular pocket that fits over the round nubs on the Clamp Center. When in place, the gear teeth should mesh as shown in the 4th photo.
5. Double over another rubber band and loop one end over the little stub sticking out just below the notch on the right Clamp Arm. Stretch the band (both sides) through the gaps on the right and left arms, and then hook the other end over the matching stub on the left arm. The entire rubber band should be stretched across the top side of the arms, which puts a slight inward  torque on the arms which keeps the gears aligned. (See photo 7)
