3D Prototype Design for Radio

I need a 3D printed design for a functional prototype. The primary requirement is to demonstrate structural integrity, with some components featuring linear movement.

Key requirements:
- Design a functional prototype for a radio.
- Must demonstrate structural integrity.
- Incorporate elements of linear movement.

Ideal Skills and Experience:
- Proficiency in 3D modeling software.
- Experience with designs requiring structural integrity.
- Understanding of linear movement mechanisms.
- Familiarity with 3D printing processes and materials.

Please provide samples of relevant work.
