A few years ago, I took a scrap piece of aluminum and machined this die. It is traditional for the opposing faces pips(spots) to add up to seven. To gett the opposing faces to add to seven, you must have the numbers 1, 2 and 3 share a common vertex. There are two different ways to arrange the 1, 2, and 3. Either clockwise which is referred to as left-handed, or counter-clockwise which is referred to as right-handed. I went with the clockwise layout and I am very happy with the final result.
