We are always on the lookout for good sources of sample and test data. Take a look at the links below and if you know of others please add them.

Especially for large models many of the above are just one giant Geometry node, which doesn't work well for clustering. We have a tool to preproces and split these models into smaller pieces, and for convenience here are some test models that have been split.

All of these are from the Stanford Scanning Repository. Before using them, make sure to read the usage rules and regulations!
