I cut the original model into 5 pieces for easier printing. I recommend printing at 225% scale.
Print the antlers with 0 top layers, 3 or more bottom layers, 0 infill, and at least 2 perimeter walls. (I printed with 0.12mm layers)
Print base with 6 top and bottom layers, 15% infill, 3 perimeter walls, and supports on. (I printed with 0.08mm)
