It’s the single version of this thing: https://www.thingiverse.com/thing:16161
It actually looks like a clean file. NetFabb says it’s a single solid without any holes, etc.
The exact steps I followed to get that error were:
1 Loaded the STL file.
2 Scaled it to 2450% because it was created in inches.
3 Duplicated the object so that I had two of them.
4 Manually dragged and arranged them to be close to center.
Is there a log that I can export, or something like that, that might help with troubleshooting?
I’m wondering if this might have something to do with duplicating an object after it has been scaled? Is that a possible source of error?
