Two-Jaw Gripper with NEMA 17 Motor — 3D Model Download

By Author • Updated: November 10, 2025

Looking for a reliable two-jaw gripper model with a compatible NEMA 17 motor for your robotics or 3D printing project? This downloadable 3D design from GrabCAD is suitable for prototyping, robotic end-effector tests, and small automation builds. The package typically includes STL files for printing and STEP/IGES for CAD assemblies, making it easy to integrate with robot arms and custom brackets.

What’s included

• 3D model of a two-jaw gripper (STL files for 3D printing)
• CAD formats (STEP/IGES) for integration with assemblies
• Mounting holes for a NEMA 17 motor and servo-compatible linkage
• Basic assembly notes and suggested fasteners

Features & Benefits

This robotic gripper design offers a compact footprint, sturdy jaw geometry for gripping small objects, and a standard NEMA 17 motor mount so you can use common stepper or geared motors. Because the model is provided in CAD formats, you can easily adapt jaw size, add sensors, or modify the mounting pattern for your robot arm.

Recommended Uses

1. Prototyping end-effectors for desktop robots and cobots.
2. 3D printing parts (STL) for rapid testing.
3. CAD integration (STEP) into multi-part assemblies.
4. Education projects and hobbyist automation.

Printing & Assembly Tips

For 3D printing, PLA works well for prototypes; use PETG or ABS if you need more heat resistance. Print the jaws with at least 20% infill and 2–3 perimeters for strength. Use M3 screws for mounting plates and a small coupling between the NEMA 17 shaft and the gripper linkage. Consider adding a thin PTFE washer at rotating joints to reduce friction.

Hydraulic Flow Direction Support Block: CAD model for system design

Saturday, October 18, 2025

This 3D CAD model represents a key component called the "Hydraulic Valve Block" (or "Manifold"), which supports and controls the flow of fluid (hydraulic oil) in a hydraulic system.

• Main Function: This block serves as the primary structure for integrating the directional control valve, pressure control valve, and flow control valve. Various passages/ports are drilled inside to allow hydraulic fluid to travel from the pump to the operating components (such as cylinders or motors) and back to the reservoir as directed by the valve.

• Importance: Using a valve block allows for a compact system, reducing the need for external piping and fittings. This reduces the chance of leaks and simplifies assembly and maintenance.

• Benefits of the CAD model: This model is a 3D file (e.g., STEP, IGS, STL) that designers can use to integrate into existing machine or equipment models for fit checks or simulations prior to actual production.
