Show HN: 3D Printing Price Check

Nice work! Suggestions:

- Unique URL for each price check page (so people can send links to their friends)

- In each orange box on the price page, show a small picture of each material. (bonus: render the object in that material. difficulty: hard)

- Minor: in the orange boxes on price page, don't include both white text and black text on the same background. It looks weird.
