There is also Blender that allows you to make sculptures efficiently without necessarily buying software like ZBrush or 3D coat to do simple things like this, and Blender is not basic but you can make detailed sculptures of excellent quality. I this file I have been thinking about using Trim to project gills curves to the base model and I have also planned to model gills as a separate object and project that object with Deform/flow to the model. I have also included 3dm file in this message. This basically the tutorial I have been trying follow and figure out how to do it in Moi3D: With FDM printer it should be ok with hard edges for details because the resolution is still quite rough. Below are a couple of examples when lure is modeled in Solidworks and 3D printed with FDM printer. The 3D printed part will be surface treated (sanded, painted, coated) anyway.

In this case I would assume that Moi3D could serve the purpose quite well because when 3D printing the part it is not needed to have 100% smooth and organic shapes for the details. First, thanks for all the tips I will test these approaches next few evenings/days.
