I enjoy sculpting these. It's kind of soothing to do. I just kings of sculpt without thinking about how it needs to look or function and just let it go where it goes. The only problem with them is that they use up a good amount of material for supports and you really need to have good support interface settings for your 3D printer otherwise the supports can be a nightmare to remove.
