Snap to Custom Grid earns its place for doing one thing cleanly: aligning geometry to a grid you define, along the axes you pick. Version 1.2 moved it to Blender's 4.2 extension system, and it ships with no external dependencies.
Snap to Custom Grid is a lightweight, efficient Blender addon for aligning vertices or object origins to the nearest point of a customizable grid. It's aimed at technical modeling, architecture, hard surface design, and any workflow where clean geometry and accuracy matter. With a single click, you can snap an entire mesh or selected objects to a grid of any size along the X, Y, and Z axes.
It works in two modes. Edit Mode snaps selected vertices, while Object Mode snaps the origins of selected objects. Axis toggles let you choose which of the X, Y, and Z axes to include, and a custom grid size lets you define spacing to match your scene scale. As an example, a vertex at X = 4.99 on a grid size of 1.00 snaps to X = 5.00.
The interface sits in the 3D Viewport sidebar (N panel) under the "Snap Grid" tab, and all actions can be undone. It requires Blender 4.2 or newer, runs on Windows, macOS, and Linux, has no external dependencies, and is released under the GPL license.
Snap To Custom Grid is best for architects and technical designers, hard-surface modelers, modular asset creators, and any workflow requiring geometric precision.
Snap To Custom Grid is completely free to download and use.
Snap to Custom Grid supports Blender 4.2 through 5.1 and requires Blender 4.2 or newer to run. It's built as a Blender add-on, and per its update log, it was moved to Blender's 4.2 extension system in version 1.2. If you're on a release older than 4.2, you'll need to update Blender before installing. For the current version and any compatibility notes, the developer's page is the place to confirm.
Snap to Custom Grid is compatible with Windows, macOS, and Linux, so it runs on all three desktop platforms Blender itself supports. It has no external dependencies, meaning there's nothing extra to install alongside it beyond a supported version of Blender. That keeps setup consistent across operating systems. For platform-specific details or changes in newer releases, check the developer's page directly.
Snap to Custom Grid installs like a standard Blender add-on. Open Edit → Preferences → Add-ons → Install, then enable "Snap to Custom Grid" in the list. Once active, open the Snap Grid tab in the 3D Viewport sidebar, which you reach with the N shortcut. From there you set your grid size and choose which axes to snap. In Edit Mode, select vertices and press Snap to Grid; in Object Mode, select objects and press Snap to Grid to align their origins.
Snap to Custom Grid offers two modes for this. In Edit Mode it snaps selected vertices to the nearest grid point, while in Object Mode it snaps the origins of selected objects. You define the grid size yourself and toggle which of the X, Y, and Z axes are included. As an example, a vertex at X = 4.99 on a grid size of 1.00 snaps to X = 5.00. All actions support undo, so you can reverse a snap at any time.
Snap to Custom Grid is listed as free in this catalog, and it's distributed under the GPL license. Licensing terms can change over time, so for current pricing and license details it's best to check the developer's page directly. The add-on carries no external dependencies, so there's nothing additional to license or install alongside it beyond a supported version of Blender.
