So, I redrew my custom shoe model in Blender because FreeCAD just can’t create geometrically-correct, smooth, complex 3D surfaces like a shoe. This one looks much better
The entire mesh in Blender is error-free. When I export it as an .OBJ file, PrusaSlicer imports it without any problems (well, it’s not oriented correctly but that’s easily fixed).
However, when I export it as an .STL file, PrusaSlicer imports it okay, but complains that the file contains 677,376 errors - out of 677,376 facets 🙂.
It seem to slice it without issues though so I assume the facets in the STL file are just missing something unimportant. But just in case: does anybody know what’s missing in my Blender model that could cause that error?
If you want to try it for yourself, the STL file is here and the Blender file is here.
(I haven’t tried to print that beast yet, mostly because the printer has been busy for work purposes all week last week and I would like to print a few test parts first. But I’m hoping to print some TPU specimens next week.)
Oh wow yeah, you’re right. I didn’t think of checking that. I flipped them and hey-presto, just like that, it works perfectly.
I learned something today. Thanks a lot!
