This is a detailed 3D printable mechanical pulley assembly featuring three rollers, designed with an engineering-oriented approach in SolidWorks. The model reflects realistic mechanical proportions and clearances, making it suitable for functional prototyping, educational purposes, or mechanical visualization.

The assembly is designed as a compact mechanism, with overall dimensions optimized for standard desktop 3D printers.

Overall Dimensions

Width: 107 mm

Height: 99.5 mm

These dimensions make the model comparable in size to a human palm and fully compatible with typical 200×200 mm build volumes.

Design Features

Three independent rollers with proper spacing and alignment

Separate solid bodies with realistic assembly clearances

Designed for FDM 3D printing

Clear geometry suitable for modification or scaling

Engineering-style construction rather than decorative CGI only

The model is intended primarily for 3D printing and mechanical use, but it can also be used for visualization, demonstrations, or educational assemblies. All parts are designed with practical tolerances to allow correct fit after printing.

File Use

Ideal for mechanical prototyping

Suitable for learning assemblies and motion concepts

Can be scaled or adapted to specific applications

Notes

This is a mechanical model, not a toy. No simulation of load capacity is included; users should evaluate material strength and print settings according to their application.
