Help Why do some meshes produce artifacts in distance fields?

[locque]

Some models always generate these artifacts in their distance field, and I don't understand why. I played around with the max error and depth parameters, but they never fully go away. I don't think the model is faulty either, it's fairly simple and I made sure that there are no holes, wrongly oriented faces or duplicate vertices in the mesh. This is what it looks like:

And here's a link to the model I used:
