"open curves" in 3D-printing model



Hello everyone,

I want to print a custom 3D model for a Raspberry Pi 3.
When I export it to a .stl file and try to print, it shows me the error “73 curves are not closed” and the log file only shows Z coordinates…

Have anyone heard about this before or can say me, how I can fix this?
(SketchUp Pro 2018 for Mac OS)

Thanks and best regards!

Upload your SketchUp file so we can see what you’ve got and tell you exactly what you need to fix.


Sorry, forgot this. Now it’s attached…


You’ve got lots of holes in your model. Some are pretty small like these on the bottom at the end of this slot.

Others are huge.

You have to close up the holes and you need to include some thickness in areas like the top of the long part of the box.


If you run Solid Inspector on it, you can see there are more than a few issues with it, rendering it unprintable:


Oh okay, thanks a lot!
Is anyone interested to earn some bucks?
I’ve 2 models with these errors and I’m a total SketchUp noob :sweat_smile:
If someone can fix me these 2 files, I’ll be the happiest man on earth. I need this for a university project and tonight’s deadline…

Here’s the second:

Here’s one. It is only a guess because there is no way to tell the thickness the missing parts should be.
I’m not interested in doing the other.
