Description
This 3D model features a precision spline shaft designed to fit snugly into a matching gear or socket, with a unique tapered multi-step base for improved grip, support, or aesthetic versatility.
The design includes:
Spline Shaft: Perfect for rotational alignment or torque transfer.
Tapered Steps: Three graduated sections for strength, style, or easier integration into assemblies.
Parametric Design: Clean geometry, optimized for easy 3D printing and customization.
Versatile Use: Ideal for mechanical prototypes, tool handles, model joints, or other creative mechanical applications.
Recommended Settings:
Print Orientation: Vertical (spline side up)
Layer Height: 0.2 mm
Infill: 50–100% for durability
Support: May not be required depending on printer precision
You can resize the model to suit your specific project needs — whether for robotics, DIY tools, or mechanical testing.
