Thank you. The balance of the whole thing is very tricky. The idea is that the 8-sided dice inside "chooses" a corner in the inside structure to land in, thereby forcing the surrounding ball to stop. Since you'll need to read the numbers from the inside, the openings are added. These will of course also add to the ability of the dice to stop at the right place. This was really the first design I made of it and here I get about 80-90% landings on the openings, which was surprisingly good in my idea. In any case, increasing the openings would decrease the overall ball shape. I'd prefer to make the inside 8-sided relatively heavier compared to the ball shape. This would allow the inside shape to better force the ball onto a corner and make it work from the inside. The whole idea is not that the ball lands on an opening, but that the 8-sided shape lands on a corner.

One thing that I do suggest though .. make the openings larger ... as the die does tend to land on a 'corner' (ie not with an opening pointing up)

Ok ... Officially pronounce this as the most innovative d6 I have seen in 33+ years of dice collecting

The reading might be a bit confusing at the start, but you'll get you used to it. Since there is an 8-sided shape inside, it lands on its corner to become a 6-sided dice. This means that the dots or pips are also placed around the corners. So, try not to look at the dots on the faces in a traditional way. Instead, look flat on the corner. 1: 1 dot on the corner 2: 2 dots on two sides next to the corner 3: 1 dot on the corner and 2 on two sides next to it 4: 4 dots on all four sides around the corner 5: 1 dot on the corner and 4 dots on all four sides around the corner 6: 4 dots on all four sides around the corner and 2 dots on two of the edges One of the photos I took show the six possible top down views after you've thrown.
