Super cool new site Ponoko is a must-check out site! You can create an object or kit (2D or 3D), choose from their variety of materials (plastic, felt, wood, cardboard, etc) and they will produce it for you. You can also set up your own store on the site where others can search items and buy your pieces. The best part? You don't have to buy say 100 kits of your design up front. It's a pay per piece per customer!!! Or you can order a bunch yourself and sell on your own. It's so easy and they have a step by step guide that tells you everything. It's like a refined version of Etsy (not that I'm knocking Etsy, I love the site but it's cool to have your items manufactured for a relatively inexpensive price). So cool, I have so many ideas racing through my head. Here is just a sample of some of the things people have created and have up for sale on the site.
