I made a simple frame for a mesh sieve.
However if I export the model as an stl and I slice it in slicer software I get a lot of mesh errors in return from the slicer software, (cura, kisslicer).
Loking at the build in DS the programm has also made a centerplate, I havent made that, I have only extruded the outher frame.
Deleting that centerplate and export it is fixing the slicing problems.
Why is there a centerplate that i havent made, is this a bug??
