This one is designed to attach to a harness. I specifically have the small "Puppia" harness (chihuahua size).
NOTE: This is a large print! I have a CR-10S 400 with a 400x400mm build plate so that's what I scaled this for. If you have a smaller machine (or a different harness) you may have to modify the model a bit.
NOTE 2: I coated mine in Art Resin to make it stronger.
NOTE 3: I used a blow-dryer to heat the wings and then molded them into the shape I wanted.
