1.68mm thick refrigerator magnet. 100% infill, 2 walls. Print face down on a textured plate for best appearance. Back side has 4 layers of black. Sliced using Orca Slicer.
EDIT: I've included a French_LH.stl file that is a layer height style for single color printers. Print it using .16 layer height. Start the print using white then pause at layer 5 and use black and finally pause at layer 8 and use grey.
The author marked this model as their own original creation.
