Model Checker is a tool written in Python for Blender. It is a Blender translation of modelChecker by Jake Kousholt, which is originally written for Autodesk Maya. I attempted to mimic its functionality as close as possible, making some changes that are more appropriate for Blender’s workflow and capabilities. It is a generalized diagnosis tool that sanity checks for naming convention, topology, UVs, and more.

Unfortunately, the code itself is not publicly available, as I believe your support should go towards its original creator.
