Very nice model overall. I printed in black PETG-CF which looks good and fits the color of the grinder well. Clip-in function for handle works nice. However, for me, it would be a 5-star model if: 1. The transition from lid to handle holder was more stiff/sturdy. 2. The O-ring was better defined. I have tried a couple and non fits, meaning that I cannot put on the lid with an O-ring in place. It's a very specific size that is needed which I have not yet found.
