Those who love to swim and want to show it! This can be made for those that love to swim to be given at either a swim banquet, swim meet or just anytime you want to show someone that you want to tell them that they are doing something they love and congrats! If made smaller it can be hung on a swim backpack. You can use it for anything you choose possibilities are endless! The gray and yellow ones are made on my Prusa Mini and the dark blue and icy blue are made on my Bambu X1C. Enjoy!!
