Hello,
I try to print a christmas tree without infill. There are a hole at bottom but in print preview the hole are closed. I don't know why.
I've added the screen of bottom as attachment, The middle (green layer) starts at layer4 but it should be holed.

Regards, Webfeger

Try the attached repaired file....S3D will load it!

If it doesn't slice how you want it to, it probably won't.
