SInce it consists of quite a few parts, here is the collection:

If you wished to do non- odd sized bases, you have to use the mirror tool, since the parts have a rotation.

So this works mormally:

But if you wanted to do this:

you need to first make half of it, put all the pieces on it. Then highlight the blue block like shown and set it to root, which you can find in the "Blocks menu", you can also see it in the following picture. Select all, copy and paste it, then rotate until it fits.

I found it best to use "Local Grid Size = 2", otherwise aiming is quite the hassle. (Not the Hoff one!)


I plan to add some important parts down the line, an inner corner for example and also some more decorative elements.

Let me know what you think and what parts you are missing
