Hollow model not printing hollow

[splicer 0]

Hello everyone. I drew this model in Sketchup Make and exported it to Cura 3.20

It is a cookie cutter. Hollow.

No matter what I try it prints not hollow.

I am using Anet A8

Please see attached .stl file, picture and Cura config.ini

The picture is after 2% and making a second pass to fill in. 

Any help would be appreciated.

Make sure the walls have a thickness.

 

Alternatively you can print the object with 0% infill an 0mm top/bottom thickness.

None of your surfaces were manifold, or what is also called watertight.

 

Your top ring was a series of flat planes that were connected on the outside rim as you can see, but on the inside, there was no connection. This made the top ring a 2D shell. The bottom walls did not have any thickness to them and therefore were a collection of open edges and again, a 2D shape.

 

Anything sketchup is not good for making 3D printable models. I do not use it, so I cannot advise you how to fix it. But I did take it into 3DS MAX and made a couple of adjustments.

This is the fixed file. I do not know if the dimensions are what you want as I did have to thicken the walls and bridge the open areas of the top ring.

 

The bottom walls that form the cutter are 1mm thick.

Thank you very much for the fast responses. I am installing 3D Max now and start learning it.
