Brain on a stand

I've created a customizable 3D-printed brain model that can be scaled to any size. I used Makerlab's image-to-3D tool to bring my design to life. The model looks fantastic, but the visible layer lines are a bit distracting. Does anyone have any advice or perhaps a print profile that could help smooth out the surface?
