Conversion to .stl for 3D printing issue

keith7777 · January 22, 2021, 1:48am

I am pretty new to Sketchup and just using the online version because my model is not complex. This is my model.

I export to .stl. Then I check my model and repair if needed using this website. https://3d-print.jomatik.de/en/index.php#SetFront

When I plug it in it says it needs repair, which has happened to me before . I repair it but then my files looks like this. (I guess I will post the picture as a comment since it won’t let me add 2 pictures here because I am new)

The top section taken out for some reason. Does anyone know why this is happening or a way around it?

Thanks!

Can you add the file for us to look at.

Problem is you have internal faces, remove them and it should be fine.

Box will give a better answer but you have a bunch of internal faces.

Better, No, potentially different, Yes.

Wow! Something so simple. Thanks for the help guys! I would have been searching for a solution for hours probably.

The work flow you use for developing a model for 3D printing is important to avoid internal faces, stray edges, or holes in surfaces. One of several options to get to the model you did is to draw a cross section and a square path and use Follow Me.
