This simple design is all about infill pattern and design. It is designed to be printed with a top/bottom layer of 0 mm in your slicer. If an infill like the custom Cura is used then a bottom layer must be laid in order for the loose part to be linked. The dimension of the model are 95 mm diameter by 6 mm thick. Scaling can be used to get the desired dimensions. 

This design with 50% continuous honeycomb pattern makes for a good trivet also. Since the infill pattern isn't “hard modeled” it makes for a way quicker and versatile print.
