I needed a 2 color bow-tie for my kid but my machine only have one extruder, so I've made it in 2 pieces. Personally I've printed it at 75% of the original size. I think it is the perfect size. But it works well in any size. 75% size Layer height 0,12mm 15% infill Print a file in a color and the other in another color. They will fit and work together.
