It always was. It always was because somethingness cannot spawn from nothingness. And in the was of the past there is the forever of the now. Only now. Only now and nothing new, for anything new would add to the infinite, yet there can only be one infinite. Only one. The universe is only becoming something new in the delusion of our minds. This delusion that makes life worth living in our perceived universe becoming.
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.
