3dhacker Group: 

   3dhacker is developed by a small but growing team of 3D printing enthusiasts. Our objectives are to support Open Source 3D printing development from around the world. Additionally 3dhacker has numerous advantages over other 3D printing resource sites. We're free to use, can tailor the site for Open Source 3D printing development ideas, and we're less interested in profit which can (sometimes) reduce "awesomeness".
