What the model looks like (pretty simple):

Here's what I get after slicing:

The tube is just gone and only 20 layers were generated.

I can confirm that I see the same results when slicing the model. I can also say that it appears to be fixed via the free online STL repair tool at https://service.netfabb.com/service.php

Interesting. PrusaSlicer doesn't report any errors for me.

PrusaSlicer didn't report any errors for me either, but I've gotten in the habit of running models through NetFabb if they don't slice properly.

Slices fine with latest git master. This one was another model that had duplicate vertices and slices fine with PS v2.1.0 when they are merged.
