I’m running a 3D printer build camp in Redmond this coming Saturday, June 25. Details are at http://eastside3d.org. While it’s probably too late to order additional printers, if you’d like to attend and watch other folks build their own 3D printers and, perhaps, learn some of the basics, including an introduction to Tinkercad, reach out to me directly. This is out first build camp. If successful we will certainly plan other, similar events.
