I liked the original holder dash95 did, but I'm too cheap to buy real Sonicare heads, and it turns out that the brand of cheapies I buy is a little too long, and I realized the very tip would be sitting in a small puddle, which I'm not a fan of. I decided to remix it by making it taller, and since I only need one slot, save plastic. I also tried to add a slope to the bottom to help drain, although I think that caused some of the print artifacts in the pictures.
