Solid Inspector² is a critical SketchUp extension used to identify and repair "non-solid" geometry, ensuring models are watertight for 3D printing and Boolean operations. Developed by Thomas Thomassen (thomthom), it is the industry standard for cleaning up complex components.
The safest and most reliable way to get Solid Inspector 2 is directly through official SketchUp channels. Avoid third-party websites that bundle extensions with malware. Method 1: The SketchUp Extension Warehouse (Recommended) solid inspector 2 sketchup download
If your workstation is offline, you can download the .rbz file manually.
If you encounter issues beyond what's covered here:
Note: Solid Inspector² requires a companion library called to function. If you install via the Extension Warehouse, SketchUp will automatically prompt you to install this library. If you install manually, you must download and install TT_Lib² separately. Common Geometry Errors Fixed by Solid Inspector² Pinpoints hidden geometry inside your solid
When the model is clean, you will see a green screen with the message: Your model is now ready for flawless 3D printing export.
If an error says "Manual Repair Needed," use the Tab key to cycle through and zoom into the specific problem areas, then fix them using SketchUp's standard drawing tools. Common Errors Explained:

In the native SketchUp interface, it is incredibly easy to leave microscopic holes, stray edges, or internal faces that the naked eye cannot see. When you try to slice a model for 3D printing or run a Boolean operation, these tiny errors cause catastrophic failures.
