Mega Arithmagon

In an arithmagon the numbers in the squares in the middle of the lines are the sum of the numbers in the circles at the ends. Usually arithamgons are triangular, but they can be any shape.

In the first triangular arithmagon below the missing number is 12. In the second one the numbers in the circles will be 7, 6 and 9.

This Mega Arithmagon works the same way. The numbers from 1 - 9 go in the nine red circles. Can you put them in the correct places and so fill the empty squares?
