I have made a few of the normal exploding boxes and I even made a pyramid exploding box but when I saw an octagon exploding box.... well! Only problem was that there were no instructions or even measurements to go on... so I sat with some cardstock and a ruler.... and after 2 Nurofen to get rid of the headache, I produced this!!
As soon as I have it all written down, I will add some instructions! ;)
This is a square version I made about our trip to Victoria Falls for my 50th Birthday!
