Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm.

Models have size 57x80 mm. You can scale it only to modify the X and Y dimensions. Do not adjust the height (Z) in your slicer! The layers would not be correct. You may print at higher layer heights below the Min Depth of 0.72mm. The Max Depth is 1.8mm and the Actual Depth is 1.8mm

If you want to hang it (need a hole) add a negative part cylinder and adjust his size and position in the model. It is possible to print without AMS by manually changing the filament (setting filament change or pause) in the slicer, depending on your printer and sw support.

These were my settings and colors for my print that you see in the picture. Your results may be depending on the filament you use.
