I ran into this on one of the models for the Voron’s Clockwork 2 (specifically, this one ).

The sliced preview shows the error, which printed… very dutifully as instructed. Image.

The print was easy enough to clean up, but now I have one of my own designs and the same thing is happening :(

Any ideas to fix it? My model was straight from Fusion 360 and appears manifold. I’m pretty sure the Voron components are also modeled in Fusion 360.
