MDF Rose Engine - Holtzapffel D Rosettes for the MDF Rose Engine

For my MDF Rose Engine I decided to 3D print all my rosettes instead of buying premade ones or having them made from acrylic using CNC. Morevover, all my rosettes have been designed parametrically so it's easy for me to generate new versions either by specifying the number of lobes (or patter repetition) and the amplitude (hight deviation between peeks and troughs). Here is a selection of Holtzapffel-D like rosettes.
