Mobile Phone Stand - Worm Gear

This model is a fully functional, foldable phone stand based on a worm gear mechanism. The design allows smooth adjustment of the phone angle within a range of 180 to 270 degrees, making it suitable for various use cases such as watching media, working, or video calls.

The model consists of three main parts:

• Gear Housing - V3
• Worm - V1 (No Support)
• Worm Wheel - V2

The Worm also serves as the control knob. By rotating it, the user drives the worm gear mechanism, which transfers motion to the Worm Wheel. This component is responsible for adjusting the angle of the upper platform of the stand.

The shape of the Worm Wheel has been designed to securely hold the phone while providing a stable and reliable support surface.

The entire structure is modular and designed for easy assembly from printed parts. The model combines mechanical functionality with simple assembly, resulting in a compact and practical phone stand.
