These are simple shopping cart key chains. They are the size of a canadian loonie I can do other sizes if you message me the coin type. I did a Height Range Modifier to iron the main flat surface in the “Objects” tab of your slicer. Ensure ironing is set to “all solid layers” for the range for best results. My best results are generally from 20-30% flow at 50mm/s. I will usually print one tag at 20%, 25% and 30% to figure out the best value then fill the plate with the best settings.
