During my junior year of High School, our school gained access to two MakerBot 3D printers. The above slideshow shows all the figures I printed during that year. I created all of the CAD files using Tinkercad. I initially created miniatures, such as the crab and the bear, to use in my Tephra campaign. However, I quickly moved into designing larger creations for table decorations, such as the crystal chalice and the clock towers.
If you want to print any of these designs out for yourself, you can see them here. Please be aware that all of my creations are under the Attribution-NonCommercial-ShareAlike 3.0 License, so anyone can remix, tweak, and build upon these works non-commercially, as long as they credit me and license their new creations under the identical terms.
