U-Shaped Clamp 3D Model

I need an intermediate 3D model of an existing U-shaped clamp, suitable for 3D printing. The model should include essential features but doesn't need to be highly detailed with textures.

Requirements:
- 3D model for 3D printing
- Intermediate detail with features
- File format: STL, OBJ, or STEP/IGES (whichever is easiest to print)

Ideal Skills and Experience:
- Proficiency in 3D modeling software
- Experience with 3D printing and related file formats
- Attention to detail and accuracy in modeling

Please provide samples of similar work. See pictures below of u-shaped nylon connector.
