3D Printed "Cootie" Key for CW/Morse Code

-----
CW or Morse Code is a way ham radio operators send messages with a simple tone of two durations.  It was a must before the days of wireless voice communications and still remains popular because it is a fun challenge.  Also, due to its efficiency messages can get through with limited power or in poor conditions.
-----
There are no shortage of morse code key designs, but in general they fall into a few categories that are discussed here.  We decided to DIY a "cootie" or "sideswiper" key and used our 3D printer to produce this design from Thingiverse.

The result was surprisingly fantastic in both look and feel.   Now, to practice.
