Mechanical Arm Holder Stand for Tablet/Phone

UPDATE
I added an additional Extender so you can adjust the length up to additional +50 mm for vertical tablet usage.

_

This fully 3D-printed articulating arm is designed to securely hold tablets and smartphones while providing flexibility and stability. The arm is clamped onto a desk and can rotate, allowing for optimal positioning. It accommodates devices from 125 mm to 215 mm in width, making it compatible with most phones and tablets.

For maximum rigidity, PLA is recommended for the structural components, while TPU is suggested for the clamp pads to ensure a secure and scratch-free grip. Whether for work, entertainment, or video calls, this adjustable holder offers a reliable hands-free solution.

The nuts for the holder and base are open on both sides. The nut for the large screw to clamp is only open on one side.
