This donut handle is way easier to use and is smooth as butter with the adaptive layer height.

I printed mine in PETG

I also have a Hexagon version of this handle

I also included both hex decors as requested. I scaled the door hex to 102%, upper hex is 100% an donut handle is 100% in the 3MF Files

Hex decor is thanks to Rob G (https://makerworld.com/en/models/34214)

Please let me know if there is anything I can do to help or if you have any questions!

Thank you for your Interest.
