I don t know what is your experience with 3d printing. So far you have shown a lot of stl designs but no actual realisation. The need of supports is not a mere foregone conclusion, especially if you print with PLA. Again you can analyse your design with Mishmixer. The supports are proposed by the Slicer app you will use. Of course, you can decide to have less support... at your own risk. When the printing is done, the supports have to be removed and at this moment i would worry for the tusks. Maybe i m wrong, never mind.
