Can someone tell me what tha f*** is happening?

Stop using SketchUp, simple :slight_smile:

The problem is, Sketchup exports EXACTLY what you draw. If your STLs have problems, it’s because you drew a model with problems! It doesn’t try to modify the mesh to make it watertight. This is simply the downside to working with a surface modeling program designed for architects, not a proper solids modeling program or 3d mesh sculpting program. It doesn’t have the “help the user” capabilities of other modeling software.

The easiest thing to do is switch to a program like F360 that doesn’t let you make bad models. But Sketchup works 100% reliably if you use plugins to find drawing problems and then fix them prior to STL export. Is that worth the effort to learn how to do? Eh. Probably not.

I also use sketchup and had have many of this kind of Issues. A easy work arround could be to rotate the Objekt in Cura. If the objekt did not stand on the button. Cura sliced it in the right way. That is not nice, but it works anytime in my cases.

@Nathan_Walkner That’s why I switched to Fusion 360. :wink:

So what appears to have fixed the issue was running the files in slic3r and using the automatic repair stl file. I’m definitely switching to fusion 360, I just have to learn it first :slight_smile: I thank you all for the imput and special thanks to @Alex_Hayden for the offer!
