I’m scratching my head to model this in Blender
can get the roundness, but the tail is a huge problem for me. From round to flat?
I thought I should try to model it in Shapr, but no idea how to approach it. Help please 
So you can see I made a trapezoid to cut from the tail. Do the same for the bottom of the tail. Use the mirror function to duplicate the trapezoid.
My mirror function and trim functions weren’t working this morning and I need to get to work so no time to fix it now.
