3D printers are here. Cheaper, better and coming soon to a table near you! This page will hopefully have a lot more to it, but here is what I have done in the 3D area.
Over the last 4 years, I have used SketchUp, a 3D tool as part of my Digital design class and as a tool to create a 3D model of a computer motherboard in my CSTEM program.
Projects done in my classes include:
Video tutorials of some of these projects (These are my only screencast examples, I made these to help my students but they do not like to watch a video, they want me to just demo it live! )
