Your design is nice. Wish I could make it for you, but I'm swamped.
A couple things:
1. You want 5 points up and 3 points down. You want the down points to be centered between the up points. However, 3 down points cannot all be centered between 5 up points. The math doesn't work. 3 down points can only be centered between 6 up points (or 9, or 12, etc.). So, you'll have to change you numbers somewhere.
2. You're picture looks like the points are razor sharp at the tips. That's not something that will be typically achieved with CNC inlays (razor sharp tips are typical with cut points - different process). With CNC inlays, the sharpness of the corners are dependent on the diameter of the end mill. Very small end mills are expensive and break easily. Therefore, many multiple depth steps are required, which means more time. Time = money. Also, no matter how small the end mill, the corner is still going to be rounded. That's why cue makers only bother going down to certain small sized end mill. Any smaller and it's just not worth it.
Good luck. If you get it made, please post pics.
