While looking on the internet for a solution I noticed that my puzzle was a mirror image of the one used in a solution, so I thought it worth documenting the solution here The puzzle consists of twelve hexagonal sticks three sticks have three notches and nine sticks have three notches, I have noticed that there is also a puzzle that has just one notch on some of the sticks. Separate out the three, three notch sticks as these are used last. Take three of the two notch sticks to make a base.
You might notice that I'm using blue tack to make photographing easier (shudder the thought!). You can see in the centre of the base there is a hexagonal dish shape, next take another three sticks and make three uprights.
Now we get to the remaining three notch pieces, notice again the three pieces form a hexagonal dish, this shape fits onto the three uprights, once you turn it upside down...
