Are you a fan of bulldogs, French bulldogs, or boxers? I've got a magnetic key holder for you! You can print it in two colors without any issues. It requires one or two 12mm diameter by 2mm thick neodymium magnets. I print it with a 0.4mm nozzle and 0.2mm layer height. I recommend enabling the ironing function in Cura for the final layer—it looks great!
