MGN12H Linear Rail 3D Model
A dimensionally accurate MGN12H linear rail reference model, including both the rail and carriage block. Save time prototyping and skip modeling standard hardware from scratch.
If you want to verify the dimensions to ensure it fits your project, you can easily measure it directly in your browser as follows:
- Click the “Open File” button above to launch the 3D model viewer in Onshape.
- Look at the bottom toolbar of the Onshape interface and Click on the Measure Tool icon.

- To measure the distance between two points or features (like the gap width or mounting hole spacing), click the first feature and then click the second. A Measure window will pop up on your screen. Here, you can instantly see the exact dimensions (such as the parallel distance, minimum distance, or X/Y/Z clearance) in millimeters.
