Does anyone have a user-friendly workflow for both identifying and fixing open edges in exported STL files?

My latest exported STL file (defaults except ANGLE set to 6) exported and opened in Prusa Slicer was flagged as having open edges which Prusa Slicer supposedly corrected automatically. But I'd prefer to identify and fix the problems within the MOI3D file before exporting so I'm not relying on the Prusa Slicer fixes.

The open edge problem is the first time Ive encountered it. I suspect the fillets I used are the likely culprit since I ended up using a combination of the default circular fillets followed by several 'const distance' fillets (first time I've used) where the circular fillet option would not work.

I've attached a copy of both the MOI file and the exported STL. I'm using an iMac (intel) with the latest OSX and the latest MOI3D beta version.

Thanks in advance for any suggestions.

PS - Just exported a version with no fillets and no open edges were reported. Attached a copy of both files.
