I can't tell how thick your model is. In general for WSF I've found 1.3mm to be a pretty good thickness. It's fairly strong and I suspect for a clip would be good. This does depend how much force will be on that clip but its a good stiffness for a lot of objects. Director 3D Tools
Cutting out some cool patterns makes most models more beatiful and less expensive, don't know if that would work on your model but i would give it a try given the pricing on this.If it doesn't look good it's not designed by us.
