This is a Canadian Maple Leaf cookie cutter. I traced this from a Canadian Flag in Fusion 360, but I did enlarge the stem for easy cookie extraction. The original size has a "cutter" that is 0.8mm average size (tried to optimize for 0.4mm nozzles). Printed on an Ender 3, at 0.2mm layer height. I will update once I have a picture of the treat that is being made using this cutter.
