At the suggestion of our customers, we've added a price break when you order 5 or more parts. Previously, you had to order at least 10 parts to receive a price break. For parts made of inexpensive materials that were easy to cut, it didn't matter much, as each part was fairly cheap. But it made ordering a few expensive parts too pricy for for many of you.
I've been looking for a good example of this kind of construction for a while now. The idea behind this is that you can assemble a series of thin pieces together to make a continuous, arbitrarily complex curvy surface. Of course, your accuracy will be limited by the thickness of the pieces.
This is a 3D surface function made from a series of thin pieces. It looks like cardboard. The pieces were laser cut.
I've also read about prototype rocket bells being created using a similar technique.
