An octagonal prism with 1x2x7's sicking out on all the sides
But It's so low on my building list, that I might as well reveal it
Just something I would like to add: if someone takes and idea from this thread it should be fair to at least say their name in the thread of the new puzzle. I'm not really saying this for me because i'm sure people have better to design
but for beginners like Sebuver who are about to start cadding i'm sure it would ge a great puzzle to start out with
Now a small question: Isn't this a bit like the "hint of secret ideas thread"??
