What's luckier than 4 leaved pyramids?

This started as a way to make a large pyramid more printable.  Adding the 4 scalloped elements makes it have built in supports if you want to try vase mode and print using the “solid” version.   

The 4 leaves add a pleasing shape on the top, and on the bottom.

Use one of the pre-shelled versions, to ensure that the shell has enough thickness to be really sturdy. I found this easier to print than using vase mode on the solid one.

The stock version is 300mm square, so please do scale it up or down as need be.  If you scale the vertical differently than the x/y, then you can get walls that are slightly more vertical and it becomes even easier to print.

I'm open to other variation requests in the comments.
