Well, that's it! It's pretty close to what I was hoping for, but it's WAY to fiddly to be totally happy with. I think the fountain part in the middle should be a teeny bit smaller, and the lion head should be smaller by quite a bit. I also have to imagine that making the fountain base in two parts - one being a hollow hex, and then a solid hex for the water inserted in the middle - would be easier than assembling the little pieces. The tabs will be much bigger, and the assembly is more straight-forward.
But, I made it! I'll try a version 2 and see how much easier I can make it. Time to buy a full version of PePaKuRa Designer!
