Thank you, yes Sweet Home 3D is a perfect program for making quick presentations.
Blender is very nice, but making these rounded sides takes 5 mins with extrusion in Photoshop, and I'm lazy!
For really perfectly rounded objects, I use Blender or preferably Verto Studio 3d.
I always use SH3D for assembly though, and being able to put light in small buttons is a great feature I really appreciate. I just wish there was a way to zoom in a lot more. I end up making my models 5 times normal size, and then downscaling when finished.

Thanks a lot for your comment!
