Tinkercad is a free software developed for 3D printers like Makerbot. Extremely expensive at the beginning and available only for architects in the industry, 3D printing is slowly moving now towards the accessible zone for personal use. Imagine you could design your own objects and print them afterwards. Using a web interface, Thinkercad allows you to create objects on your computer and export them as STL files for your Makerbot 3D printer.
