Designing a manifold and keep getting open Sliced Areas

I am having an issue in the slicing of a manifold print and cannot seem to resolve it. Is there anyone who can assist me so I can fix this issue ?

Can’t really tell you anything useful from your screenshot. Share the .skp file.

sorry got it

How did you create this model? It’s really quite dirty.

After cleaning it up and creating a component, SketchUp reports it as a solid.

And no problem in the slicer, either.

I gather you have a Pro subscription to SketchUp. You should update to the current version. It’ll handle the smaller geometry more easily.

Thank you and yes it seems upgrading is good too, I will see how to fix this on my end. No possibility to share the file as solid ? even STL

Yours is on the left. Mine is centered on the origin. I set model units to Meters to allow for smoother surfaces and I turned off Length Snapping and increased Display Precision. I also drew out the various circles so their vertices are on axis which makes the model easier to work with.

BTW, there’s no need to scale the model down before exporting the .stl. In the export options set the export units to Model Units or Meters and export.

Thank you so much, I have a lot to learn still
