This bow tie is all laid out in a single print, it has two articulating pieces to make a fun moveable bow just like a real bow tie. This articulation is accomplished with two print in place 180 degree hinges. The clip prints separate and easily goes on and off the tie from the center.
I have attached a 3MF file with all my settings built in, you can print it in PLA and it will work just fine, but if you push the bow pieces together too hard a small crack may form on the hinge. This does not fully break and the bow tie will still be fully functional, but I haven't had this problem with PETG so I recommend using it instead.
