Detecting and Fixing Non Manifold Mesh

Hi! I'm working on some custom wheels (specifically TPU rims) for my robot. I've never run into this issue when slicing in Cura before, but a friend says it's non-manifold mesh. I don't see any problem geometry after inspecting. I've tried removing each feature in Onshape one by one and re-slicing in an attempt to isolate the problem, but am still coming up with the same issue.

    It my be something to do with the Cura settings. I tried it in Simplify3D and Prusa slicer, both seemed to generate the gcode without any problems

    Agreed - Cura is slicing it fine for me. This feels like a slicer issue; it shouldn't look the way it does. A few factors to twiddle: mesh resolution and format on export, part rotation or translation, slicer settings (including support).

    You could share your exported STL; maybe it really is a bad export.

    Separately, I'd recommend making the wheel in a way that doesn't need support, i.e., such that it lays flat on the build plate. Else, one side will be very ugly b/c of the removed support.
