Like this? I made the bulky part of the scouter using an ordinary rectangle + a lot of cuts... I made 25% of it, then cloned it 4 times and attached them all together and welded the vertex's.
I am not nor have I ever been a sketch artist, I could never draw a straight line, lol... but this 3D thing is a lot of fun for me.
P.S. if it's too bulky I could easily cut like 20-30% off of the back portion to make it look thinner like in the picture. I kept the pieces unattached for the sake of future tweaking.
