Why is this so expensive?

Hi guys,

Attached you can find my uploaded file. It's a sphericon and just a few inches on all sides.

I believe it's hollow, so why does it costs $184?

Thanks for your help.

Sorry, but it's NOT hollow. I'm not sure what software you're creating this with, but it is only a single shell with no interior geometry.

I'm using Google Sketchup.

What's the best way to get interior geometry?

Thanks for your help.

You should be able to export it into something like Blender. Blender has a shelling operation. I think it's called solidify (under "object:mesh:faces:solidify"). On the right, there should be a slider/number input for how thick you wish the walls to be (make sure not to input backwards, else it will GROW out! ).

I can talk you through the full export/import and buttons in Blender etc if you wish to do it.
