An example of how 3D printing can improve everyday life:
1 elastic band, <10 minutes design, <10 minutes printing = <3 3D printing!
*Note for Jon: ping in this context is intended to indicate a fast moving object that may make an audible noise like a ‘ping’ when it contacts something. It highlights the unintended outcome of the DIP switch departing contact with the bread board at sometimes impressive escape velocities!
